I'd take McKenzie and Johnson and not give it a 2nd thought. Jones would be an impact guy sooner IMO, but I don't think we win that battle with the MS Juco handlers. I think Settle is a longshot.
I wouldn't call Settle a long shot because in the end we are going to be in his top three, but I do doubt that we get him. Being in the top three for someone does not equate long shot though...
Hawks are definitely a multiple front team. Carroll called it "running a 4-3 with 3-4 personnel". They do some crazy stuff with their front 7. I once saw them successfully drop their NT playing the 0-tech into coverage on a TE. Interestingly enough the one time we did that last season with Corey Miller at the nose (not sure if he was lined up over center though) it completely confused Connor Shaw and ended up with him getting sacked from behind.
