Looking at the glass half full perspective...
Thieneman instantly makes this defense better and provides the sort of playmaker the Bears will need in the secondary, particularly in a pass-heavy division, and ostensibly gives them a locker room leader on defense. He fell into their laps, but he was a fantastic pick.
Jones addresses a need, provides interior depth, and might be the starter coming out of training camp if he truly has the goods. I preferred Hecht, but I like the pick.
Roush makes sense for how Johnson likes running his offense with 2 and 3 TE sets. He provides depth at the position and should be versatile enough to benefit special teams.
Thomas is...fast and a kick returner, so he should be good at that? I really hope I'm dead wrong when I think "Velus Jones" any time I see this pick?
