Newton and Murphy.
Murphy is really hard to have a good rep against, and really easy to lose to.
He has instinct that puts him a step ahead of most blocking schemes and his strength and center of gravity allow him to simply control dudes in the run game and work them in the pass game.
I think if you want a SOLID DT he's your guy.
He's just not rare in any area ... so Kris Jenkins is the same type of player, just not as strong or fast.
Newton for me is a different animal. And if he had tested how I expect (4.8 40, 30 reps, crazy 10 yard) ... I'd have him in the top ten.
I think he'll be a steal if he slides...
For me, he's a little less "in control" and more "disruptive" ... which is my personal preference.
He may lose some reps, but when he wins he destroys the play super fast.
How early you win on an inside rush is the difference between a back being able to make a cut or a QB being able to get out and possibly make a play.
It's a tough thing to try to replicate Donald... but I thought he was better than Cancy was last year and played against tougher competition and was playing hurt this last year.
