Biggest surprise: Most former NFL quarterbacks turned head coaches love to surround themselves with as many QBs as possible. But Redskins coach Jim Zorn is taking a new approach after placing Colt Brennan on injured reserve with a hamstring injury and a previously undisclosed hip injury (torn labrum). The Skins also released Brennan's competitor for the No. 3 job, Chase Daniel, but there's a good chance that Daniel shows up on the practice squad. I don't think Brennan will ever play for the Redskins again -- even when he's healthy. The two sides will reach an injury settlement and go their separate ways.
Mildly surprising to see running backs Anthony Alridge and Dominique Dorsey both end up on the chopping block. Alridge missed too much time in camp and then he had ball security issues. Dorsey and Alridge would both be practice squad candidates. Cody Glenn was sort of a head-scratcher from the time the selection was made.
Trent Shelton's definitely a practice squad candidate. The rise of seventh-round pick Marko Mitchell out of Nevada made it impossible for Shelton to make the team. The good news is that Shelton has already sent out a Twitter update indicating that he'll be signed to the practice squad.
No-brainers: You knew Marcus Mason was going to make this team as the fourth running back. And by the end of the season, it wouldn't surprise me if he's the backup to Clinton Portis. He's just a nice change-of-pace. I thought it was no-brainer to keep him around. I think some folks might be a little surprised to see Jeremy Bridges go, but the Redskins just thought he would stand in the way of some of the young guys. He didn't look that good to me in the preseason, so I don't have any problem with that decision. You hate to see a guy like Alex Buzbee work his tail off to rehab from knee surgery and then not make the team. There's at least one cornerback still on this team (Tryon) because of where he was drafted in '08, and that's a shame. I liked the way safety Lendy Holmes tackled in the open field. Maybe there's a spot for him on the practice squad.
What's next? The Redskins are old at defensive end. Vinny Cerrato should take a peek around and see if any talented, young pass-rushers were released. But for the most part, I think the Redskins are pleased with their 53-man roster. They'd hate it if someone signed Daniel, but I don't think that will happen.
