I think this guy a very good grab. However, we do need to start looking at some bigger LBs. Not everyone is going to be David. I wanna see some 6-2 220 (a solid frame to add 20 or so pounds). Lambert would be a huge grab we if could get him IMO.
This guy is 6-1, 220. So I would say he fits your mold. I'd guess since he's getting here for spring(hopefully), and he learns how to really lift I'd bet he'll be 235 to start the season. I don't think you need Mike LBs any bigger than that, b/c then they can start losing speed. And David is big enough to be a Will in the B1G. It's more about athleticism and reading. You have to read, then if you are athletic enough you can get by any OL in the B1G.
