I'm assuming you like Jake Long so much you mentioned him twice
Seriously, my worst fear is to see Chris Long on the board at #7. I'm in ACC country so I've seen quite a few UVA games and he is a fine player. There are a couple of things to consider:
1) He played in college at about 6'4"/285 lbs.
2) He played DE in a 3-4 alignment.
3) He did his best work when penetrating into the backfield.
This would make him the next Jarvis Green, not the next Willie McGinest...and we already have the current Jarvis Green under contract. Long might be able to transition to LB quickly and become a standout, but there is no game evidence to say one way or the other. That kind of risk is unsettling for me at #7.
There are also a lot of teams with CB needs. While I agree with the feeling that #7 is too high for just about any CB (at least in the Pats value system), I also think that you could see a dozen CBs come off the board between the middle of the 1st and the middle of the 2nd.
My ideal scenario if Gholston is off the board is to trade back to about 15 (still get a 6 year deal) or 20 (less money and more trade value) and pick up one of the top CBs. After the rest of the teams panic and scoop up the scraps, the Pats can likely wait well into the second day to pick up another CB at a good value.
