The Eagles insisted all spring they were copacetic with Kurt Coleman opposite Nate Allen, backed up by 2011 second-rounder Jaiquawn Jarrett, who barely got on the field as a rookie. Then, after reviewing all the spring tape, the Birds signed veteran O.J. Atogwe. I'll be shocked if Allen doesn't start, but after that, who knows? Coaches built up Coleman all spring — not sure anybody works harder to improve — but he was a 2010 seventh-round draft pick for a reason. He isn't big or fast, and he misses tackles. Coleman is a guy you want on your team, maybe not as a starter. Atogwe, franchised by the Rams 3 years ago, is 31 now, and he was cut loose in January by a 5-11 Redskins team. He missed all the Eagles spring work and will be learning the defense from scratch at Lehigh. The guy I think is on the roster bubble here is Jarrett, the former Temple star, who as a rookie didn't seem to have the frame or the quickness to back up his big hitter rep. It's not that big a deal, in a lockout year, for a rookie not to get a lot of snaps from scrimmage, but Jarrett couldn't seem to make himself useful on special teams. That's a red flag.
