Per Geoff Mosher of the News Journal, rookie Danny Watkins will start this Sunday in Buffalo. Less than a week before the Eagles' opener in St. Louis, the Eagles signed Kyle DeVan off the scrap heap and plugged him in as the starting RG. DeVan was formerly an Indianapolis Colt, and was therefore familiar with Howard Mudd's blocking schemes, so the move made sense. At the time, Watkins was coming off several bad performances in the preseason, and there were major concerns about playing a rookie center (Jason Kelce) right next to a rookie RG.
Unfortunately for the Eagles, DeVan has not played well. He has been bullied in short yardage situations, and Pro Football Focus credited (or perhaps discredited) DeVan with giving up 2 sacks against the 49ers on Sunday.
Fortunately for the Eagles, Kelce has played well and has been a pleasant surprise, which should quell some of the concerns about 2 rookies playing side by side.
