Michael Hamlin doesn't impress me at all. I'm just not a fan.
We need a free safety who covers our CB's mistakes and capitalizes on QB's mistakes. Teams aren't afraid to go deep on us. They know it will either be caught, end up as Pass Interference, or safely hit the ground. You do that against Baltimore, Indy, Philadelphia, and some other teams and that free safety will make you pay.
Darren Woodson was a strong safety, heck, he was a linebacker at Arizona State, but he had so much smarts and feel for the game, he got by at Free Safety for several years. Ken Hamlin is almost never there to make a play. At least Roy is a force against the run. He couldn't cover Wade Phillips on a fly route, but he will hit you.
Ken "the Hammer" Hamlin needs to go back to his High School and remember the fundamentals of wrapping up ball carriers. It's a technical problem and can be fixed with coaching and a willingness to improve. Roy's career can be saved if the Scheme allows for his strengths and does not put him in vulnerable positions.
