I doubt he'll get the vote, but I agree he's playing on that level. His tackling and run defense were very solid yesterday, and his coverage ability is elite. If the Pats let him rush more, he would rack up the numbers. Collins and Hightower are as solid a pair of LBs as there is in the NFL right now.
I'm sure the Pats would like to rush him more, Hightower as well (they started the season doing it), but they're limited because of the injuries, Mayo's in particular. But you're right about Collins. He has done nothing but improve as the weeks have gone on. Second rounder? May end up being a draft steal. He is beginning to put the mental aspect of the game together with his unique skills and athleticism. He's a Swiss army knife-type player and he, much like Revis, adds an element of flexibility for BB to deploy the D in many different ways.
I don't think D coordinators are planning for him yet and telling their QB's to always be aware of him, but I don't think that's far behind. I don't think he's a Pro Bowler or All-Pro yet, but it's hard to imagine he won't be sooner rather than later. If Mayo can stay healthy, NE will have a LB unit that will rival the best in the NFL, as they have skills that complement one another's very well.
Not only was he good against the run, he seems to be improving dramatically at coming off blocks. If he and Hightower keep playing at this level for the rest of the season, they would deserve to be All Pros.
His inability to shed blockers definitely showed up big in the first quarter of the season. But he has definitely gotten better in that area, as you've stated. I think yesterday was probably his best game in that regard. He was making plays all over the the field, and he tackled extremely well when he met the ball-carrier.
Hightower is playing extremely well and has done a very good job mitigating the loss of Mayo. I think he will get Pro Bowl consideration before Collins, assuming either of them gets any consideration.
Collins has been good, but I think if any LB was deserving of a pro bowl spot, it's Hightower. He's been consistently good, if not great since week 1. And he's done that playing multiple positions.
Hightower has been incredible. In fact, I think that it is very much an underrated story line of the season, just like Chung's performance. He really has shown that he's learned the game. That was his true limitation to this point. BB finally stopped using him to cover so much too. I think that has helped him much like it has Chung. They'll never completely shed coverage responsibilities obviously, but BB is limiting how much he has asked them to do it.
