After the earlier news that the San Diego Chargers had let go Hal Hunter as the team's Offensive Line Coach and Charlie Joiner as the Wide Receivers Coach, some (including myself) speculated that Mike McCoy had simply let them go because he already had coaches picked out for those spots on his coaching staff. The quick hiring of Joe D'Alessandris and Fred Graves certainly supports that theory.

D'Alessandris was hired by the Buffalo Bills as part of Chan Gailey's staff, and he was fired for being a part of Chan Gailey's staff. According to Football Outsiders, here's how the Bills' offensive line ranked during his tenure there:

2012: 8th run blocking, 10th pass blocking

2011: 12th run blocking, 1st pass blocking

2010: 20th run blocking, 17th pass blocking

In 2009, before D'Allesandris, the Bills ranked last in the league in pass protection, so there's little doubt that he will be able to help the Chargers (last in the league is pass blocking in 2012) improve in that regard.
