It's hard to ignore the fact that the Packers RARELY choose to move on from somebody and watch them excel elsewhere. I really don't care about the 'feelings' of Adams or us as fans, but I think the safe and likely correct bet is that Adams will have a couple of really nice seasons in LV, taper in year 3, and be either cut or an albatross thereafter.
The Packers were seemingly willing to sacrifice the backend part of that deal for the high performance on the front end, but now instead get to reap the rewards of a 1st & 2nd along with cap room to actually help fill holes without worrying about the backend part of the deal at all.
