Brown's a good depth player and it wouldn't even be that surprising to see him start if the rookies aren't ready yet. I like Lewis better because he makes plays on the ball, but he also takes more risks to do that.
Awuzie is our best corner until proven otherwise, but it's close between Brown and Lewis out of the returning ones for various reasons. It will be interesting to see who moves up in the pecking order. Will Diggs seize a starting spot right off the bat? Will Robinson catapult to the top? Is Worley an option for a starting corner job?
The only guys I'm counting out are Canady and Goodwin, who I don't think will make the team now. Both of them are here more for special teams IMO. There's also Savion Smith, who I think is in a similar boat, and Chris Westry. I find Westry intriguing, but I can't see him beating out these others, so it may be another year on the practice squad for him.
