Sounds like you have been reading Bleacher Report.....even if you don't want Luke....Connor isn't really comparable.
I gave up on BR a while ago, but the write ups I see just remind me of Connor and no, it's not because theyre both white. Both are very instinctive, heady football players with excellent technique and fundamentals. Both are tackling machines but both lack the knack for big hits and forcing fumbles. Luke's big advantage is his speed and coverage ability.
Someone on NFLN compared him to Vilma, which I would love and if that's a more accurate comparison then great, but what I've read just screams faster Dan Connor.
They only player that would really disappoint me at 9 would be Ingram, just because I don't think he's a good fit in a 43 and his short arms will hurt him against NFL OL's.
