ORCHARD PARK Youth Shaq Lawson Jerseys , N.Y. (AP) — The Buffalo Bills shook up their coaching staff by firing offensive line coach Juan Castillo and receivers coach Terry Robiskie following a 6-10 finish.A person familiar with the decision confirmed to The Associated Press of Robiskie’s firing following his first season in Buffalo. The person spoke on the condition of anonymity on Wednesday because the team has not announced the move first reported by Sirius XM’s Alex Marvez.Earlier in the day, general manager Brandon Beane said Castillo was fired Tuesday.The shakeup comes after Buffalo’s offense finished 30th and despite rookie quarterback Josh Allen showing gradual development in winning three of his final six starts to finish 5-6.Castillo also oversaw the LeSean McCoy-led running game, which sputtered during his second season in Buffalo.The Bills ranked ninth in the NFL with 1,984 yards rushing, though Allen accounted for nearly a third of that with a team-leading 631 yards. McCoy had career lows with 514 yards rushing and by averaging 3.2 yards per carry.Buffalo’s patchwork offensive line never entirely jelled in having difficulty replacing the offseason losses of center Eric Wood and guard Richie Incognito.“There were some times throughout the season where I didn’t think we played well enough; we were out of sync up front,” McDermott said during his season-ending news conference on Monday. “That’s an area that we have to look hard at this offseason.”McDermott and Castillo previously worked together with the Philadelphia Eagles. Castillo was the Eagles offensive line coach before taking over as defensive coordinator after McDermott was fired following the 2010 season.Robiskie was hired by the Bills to replace Phil McGeoghan, and inherited a mostly young and unproven group of receivers behind returning starter Kelvin Benjamin.Benjamin’s production regressed to the point he was released with four weeks left in the season.Robiskie did play a role in developing second-year receiver Zay Jones and undrafted rookie Robert Foster. Jones led the team with 652 yards receiving and seven touchdowns, while Foster established himself as a starter over the final month of the season. The Buffalo Bills offensive line didn’t play well enough in 2018. They fired offensive line coach Juan Castillo and replaced him with up-and-comer Bobby Johnson. What does that mean for the vacant right guard spot and backup guard Vlad Ducasse, who was benched halfway through 2018?Read our information and then vote in the poll at the bottom of the article.All-22 Review(Read the entire analysis by Jeff Kantrowski)Vlad Ducasse isn’t a player who’s bad enough to be sent packing without a replacement. Working in his favor, Ducasse has played both left and right guard, which means he can be in the competition for two spots and could also be considered a valuable depth player as a result. Working against Ducasse is the fact that Buffalo has already slotted in Wyatt Teller ahead of him.Ducasse doesn’t lack for power or athleticism, but little things prevent him from always rising to his potential. Athletically, Ducasse seems capable of blocking on the move Shaq Lawson Jerseys Stitched , but often places himself in awkward scenarios. Ducasse’s strength lies in his, uh...strength. Put a man in front of Ducasse and dare him to go through the guard and you have a dependable blocker. Ducasse isn’t a mauler and shouldn’t be expected to always drive his opponent backwards. He is a solid anchor and will give the quarterback time to go to work.The biggest factor could be Brian Daboll’s intended scheme. Daboll has gone on record as coveting a variable scheme, where linemen shift game-to-game among blocking concepts. Ducasse’s best asset is his ability to anchor. Beyond that, though, Ducasse struggles, which greatly diminishes his versatility. Is that enough to call it quits with Ducasse? It very well could be.Salary cap info(Read the entire article by Dylan Zadonowicz)Ducasse’s contract is like a get-out-of-jail-free card. The numbers provided by Spotrac:2019 cap hit: $2,083,334 millionSalary due: $2 millionDead money from signing bonus: $83,334Cap savings if cut: $2 millionIn-house replacement options(Read the entire article by John Boccacino)Rookie Wyatt Teller, entering his second season, displayed a ton of promise in eight games (seven starts), allowing only eight quarterback pressures with no sacks and five committed penalties. The fifth-round draft pick proved himself capable in pass protection, though his run-blocking has room for improvement.Jeremiah Sirles Youth Frank Gore Jerseys , who recently inked a one-year contract extension with Buffalo for the 2019 season, was active in 12 games (five starts) and saw time at both tackle and guard. He is a swingman who is expected to compete for a roster spot in training camp. He could start in a pinch but shouldn’t be handed the job.Lastly, there’s Ike Boettger, an undrafted rookie free agent out of Iowa who spent the entire off-season, training camp and the pre-season with the Bills. After serving as Buffalo’s back-up right guard, he was released before the regular season. Boettger eventually released by the Kansas City Chiefs and claimed on waiver by the Bills and appeared in the team’s last four games.Free agent replacement options(Read the entire article from Sean Murphy)Mark GlowinskiThe 26-year old graded out as PFF’s 17th-best guard this season, earning a 69.8 overall grade on the year. His improved play was a big part of the reason that the Indianapolis Colts were able to keep quarterback Andrew Luck healthy. Buffalo’s new offensive line coach, Bobby Johnson, was on the Indy staff last year as assistant offensive line coach.D.J. FlukerThe 28-year old Fluker graded poorly in PFF’s overall rankings (49.8 overall; guard No. 70); however, the outlet noted that he only allowed nine pressures in ten games this year. A huge negative is the number of penalties he committed last year—nine—which brought his career total to 43 penalties in 74 career games.Rodger SaffoldThe Los Angeles Rams will play in Super Bowl LIII in February, and it could be their veteran guard’s last game with the team. Saffold is 31 and coming off a season where PFF graded him as the seventh-best guard in the NFL, as he earned a 73.8 overall grade. Ramon FosterThe veteran has been a dominant force on the Pittsburgh Steelers offensive line since 2009. He has been remarkably durable, starting 14 games or more in every season since 2011. He has continued to perform at a high level despite his advanced age (Foster just turned 33) Frank Gore Jerseys Stitched , and PFF graded his play this year at a 69.1, which was sixteenth among all guards. Matt SlausonAnother fantastic veteran, Slauson signed with the Colts this year and made it through 5 games before fracturing two vertebrae and landing on injured reserve. He was solid in his time in the lineup however, earning a 66.8 from PFF, which was the nineteenth-best score among guards. At 32 years old, he would be someone to sign to an incentive-laden deal. When he is healthy, he is still among the best guards in the league. Andy LevitreIt won’t happen...would it? A reunion with Buffalo’s second-round draft pick from the 2009 NFL Draft would be something, but at 32, he seems to be on the decline, as he has had his season end prematurely each of the last two years due to triceps muscle tears. 2019 NFL Draft replacement options(Read the entire article from Andrew Griffin)Tier ICody Ford (Oklahoma) Michael Deiter (Wisconsin)Dalton Risner (Kansas State)Tier IIChris Lindstrom (Boston College) Beau Benzschawel (Wisconsin)Connor McGovern (Penn State)Michael Jordan (Ohio State)Garrett Brumfield (LSU)Tier IIIRyan Bates (Penn State)Dru Samia (Oklahoma)Ben Powers (Oklahoma)Short scouting reports on each draft-eligible player available in our feature-length article.Mark Konezny-USA TODAY SportsNow it’s your turn, Bills fans.
