The Buffalo Bills hosted free agent offensive lineman Matt Slauson on a visit this past Friday at One Bills Drive, one day after Slauson - released by the Chicago Bears last weekend - made a similar visit with the San Diego Chargers. Buffalo had been eyeing Slauson as a potential option at right tackle, per ESPN's Mike Rodak, and at minimum found his ties to head coach Rex Ryan and his versatility up front appealing.
On Saturday, Slauson chose the opportunity to start in San Diego on a two-year deal over the opportunity he had with the Bills.

Slauson's decision leaves the Bills with 14 offensive linemen on their active roster. With four positions on the starting unit settled (including, seemingly, the right guard spot), the only question marks entering training camp appear to be at right tackle and the reserve interior spots.
Jordan Mills ended the 2015 regular season at the right tackle spot, and it's fair to expect that he'll begin training camp in that role ahead of Cyrus Kouandjio. Seantrel Henderson could re-claim that role depending on his health status, but Mills has the best shot at opening camp with the ones, in our estimation. Meanwhile, on the inside, veterans Fernando Velasco and Ryan Groy have the best shot at earning gigs, with a handful of intriguing project-types behind them. Slauson might have fit prominently into both of those conversations.
Here's an early stab at the Bills' depth chart along the offensive line.
| Pos. | Starter | Backup | Reserve |
| LT | 77 - Cordy Glenn | 66 - Seantrel Henderson | 73 - Marquis Lucas |
| LG | 64 - Richie Incognito | 72 - Ryan Groy | 60 - Jamison Lalk |
| C | 70 - Eric Wood | 61 - Fernando Velasco | 67 - Robert Kugler |
| RG | 76 - John Miller | 68 - Cyril Richardson | |
| RT | 79 - Jordan Mills | 71 - Cyrus Kouandjio | 74 - Keith Lumpkin |
