I watched all the games I could from A&M this year and even though I really like Murphy as a good character player I don't think he'll be as productive at the next level.
Here is a good article about Terrance the person
First I think he's a little undersized at 6 foot. Also I don't think he has great football speed. Also he doesn't have great hands or excellent ball awareness.
Basically he's good but not great in nearly all of the catagories. You can bet he'll work hard, as he has an excellent work ethic, but that just begs the question of why he wasn't better at this level if he already works that hard?
I think Murphy has peaked sadly.
