You are wise. He's basically an unknown to us but the football people obviously see some talent in addition to being a low risk gamble. It's probably a low round draft pick for his services. It's also TD looking a year ahead, knowing Spikes returning to his previous form isn't a sure thing.
Don't forget, we may receive a comp pick or two for losing Jennings and Pat Williams, in addition to the extra 3rd rounder for Henry.
