Personally, I think a better draft option at ILB for the Pats will be Kai Parham. His draft stock is plummeting due to a slow 40 time - but 3-4 ILBs don't need to be as fast as 4-3 MLBs. Parham is a great run stuffer, played in a 3-4, and has great instincts. The Pats could likely pick him up in the 3rd round, perhaps even on day 2.
There are many very good OLB prospects who will be taken in late round 1 and very early round 2 - I'd much rather see the Pats take one of those guys in the first round, rather than an ILB. Greenway, Carpenter, Lawson, etc..
