I suppose the areas of need you'd have to consider, if you really did want to trade a DB, would be these:

Inside linebacker

Offensive tackle

Tight end

But realistically, would another team trade what you really need - a starting inside linebacker, say, who's better than either Hawk or Jones/Lattimore/Barrington - for a guy like House, who has yet to prove he can stay healthy and play at a starter's level for a whole season? What you might get is an inside linebacker who, like House, is seemingly starting to break out, but is far from a proven commodity.

Then you'd put him into your defense and hope he could learn it all quickly enough to unseat one of your starting ILB's by the last three or four games of the season.

I dunno. I thought it'd be fun as a fantasy question, this idea of trading House/Hayward/Hyde, but the more I think about it, the dumber it seems.

I suppose I'd be most willing to trade Hyde, but what would you get for that? A backup player, probably.
