According to Scout.com, the Patriots have paid a lot of attention to the running backs in Indianapolis. Specifically, LenDale White from USC. Furthermore, the article insinuates that the Pats may have to (and are considering) trading up to get him as he will more than likely not be there at 21:
LenDale White confirmed the Patriots interest:
I would love to see LenDale White in a Pats uniform. He is a tough, between the tackles runner with solid speed. His numbers at USC could have been dramatically different (on the plus side) as he had to share time with Reggie Bush. I do not, however want to see the Pats give up too much if they have to trade to get him. Who knows, he may slide to 21? Wishful thinking.
