Justin Smith is just a badass son of a bitch... I don't get too hung up on size.
As for giving up the edge - sorry, that is not acceptable. Justin Smith would never allow himself to be turned and ridden out of a play the way I see Jones sometimes.
As it said in the write up 3irth1 posted - I didn't write that. Jones does, in fact, have a bit of a history of 'playing down to the competition'. I probably watched more film of Jones than I did anyone else, it was enough to scare me off him. I like his ability, but I'm not sure what we're getting.
