Slauson knows the Bills coaching staff well, having previous stints with Rex Ryan on the Jets and Aaron Kromer on the Bears. This could work in Buffalo's favor. No one can argue that adding Slauson would upgrade Buffalo's offensive line.
However, what role do the Bills envision for Slauson? According to Chris Brown, the lead writer on BuffaloBills.com, the Bills see Slauson as a backup. From his Fan Friday article:
I think the Bills would like to add him and they do have one open roster spot at this point. The money saved by signing Cordy Glenn to his big extension helps make that a greater possibility. Have to see what Slauson is willing to accept if he likes what his role would be, which at this point would be a backup. Not certain he’s ready to accept such a role.
It's an interesting note considering the right side of Buffalo's line has had its issues. John Miller struggled mightily as a rookie as right guard and the right tackle job is currently seen as a two man competition between Seantrel Henderson and Jordan Mills. Slauson realistically should be given the opportunity to compete for the starting role at right tackle and if he cannot win that job, you can at least kick him inside to right guard where he could compete against Miller.
If Brown is correct and the Bills view Slauson as a backup, he may take a job elsewhere. He's already made a visit with the Chargers and other teams will likely pursue a player who has started in 85 career games.
