Normally, i would say that panthers scenario sounds likely, but not in this years draft. There are a ton of 1st rd LB's in this draft and they can easily get a great one at the end of the round, where in years past that wasnt the case. Now, id they feel they are only a few players away, and dont mind giving up the picks then just maybe, but they are at #27 and they would have to give up a considerable amount to basically move up a whole round, which is unlikely.
I totally agree with you on the 49ers and Huff. I think both the niners and oakland's Safety situations are worse than ours, and he could go to either one of those teams.
This is probably the most likely scenario to play out. Denver is only a few players away, and their offense misses a TE and they have the picks to move up easily.
Lets not forget about Minnesota. I think Denver and Minn both want to move up, the Vikings are hot on getting a QB, watch for them.
