Too bad Rolle is spilt milk. It would be highly unusual for Thompson to overpay for any position. Instead, I think he's more inclined take a flyer on some talented guys who, for one reason or another, may have slipped below most teams' radar. And with a little luck maybe they could provide rare value as fill-ins at the back of the roster. Here's just one specific example:
Brandon Hardin, CB Oregon State, was drafted by the Bears in the 3rd round in 2012. He's 6'3", 220 lbs. and ran a very impressive 4.38 40 on his pro day. He was the Pac-12's best gunner on STs for three straight seasons, an absolute beast. He's known as a really big hitter -- too big, sometimes. He's also known to be a scholarly, high-character guy. He's a natural CB even at his size, so, naturally the Bears chose to convert him to Safety.
He was injured in his first camp with the Bears (stinger) and was stashed on IR. He injured his shoulder (similar to Davon House) during a preseason game during his second camp with the impatient Bears (new) Trestman regime, and he was released on the final roster cut. The Jets signed him to a futures contract during the season and he again got injured (foot) near the end of his third camp. The Jets then cut him. He's still only 25.
Talent does not seem to be his issue, but minor injuries have been. Nothing career-ending, but rather of the nagging variety that guys sometimes are eventually able to put behind them, like Mike Neal finally seems to have been able to do. With his potential he could back-up all positions in the defensive backfield and also could possibly replace an aging Jarret Bush as a gunner/reserve DB. Chris Banjo can't be taught to be bigger and faster like this guy already is.
Drafting at 30th the team would seem to have no other choice but to explore several FA options such as players like this one. As a minimum wage value guy for the 80 man roster, what's not to like? FAs like him auditioning on the 80 man roster just might produce a winner or two. I'll wager that some of you know of an available FA out there with a similar profile.
