Trade vets for draft picks.
Green Bay could use a TE like OD.
An injured TE? Who would trade draft picks for that exactly?
Here's the problem with trading and the NFL and why you don't really see blockbuster deals happen at the trade deadline:
1) It's really early in the season and there are plenty of teams who are nowhere close to playoff contention who think they still have a shot. They will want to keep the few good players they have on their roster in hopes of pulling a 2012 Vikings and just getting to the wildcard game.
2) Coaches and GM's who do not believe they are on the hot seat (again, because it's still fairly early in the season) are not going to trade away key players for draft picks because that would appear that they are throwing away the season when it's barely half over.
3) The guys who are apparently available (Nicks, Allen, Britt are the ones I hear the most) are either in a position that we just invested a high draft pick in, and are going through a change at a position that is crucial to their involvement on the team (WR's), or, are on the last year of their contract and will be basically an 8 game rental and then you have to re-sign that player (Allen).
Jared Allen is the only guy I have heard bandied about being traded (and really that just started today, and with Seattle) that I would have a passing interest in as Texans fan, and really, I cannot find it in myself to be upset if they "passed over" Jared Allen. I might give up like a conditional 4th or 5th round pick for that particular player, but I doubt the Vikings would just give up Allen for that low of a price.
