*giggles* Sure, but he'd be an idiot to accept. Jackson isn't in good health, and his team can't block worth a damn. Miller is decent, but he's so far below gates level that it's kinda pointless.
If you're looking to upgrade at TE, try Steven Jackson + Heath Miller for Dallas Clark + Something.
Jackson + Miller for Clark is overkill, so you'll either have to offer a lesser RB, or try and get something else out of the deal. I'd look at that, because you might actually get something out of that deal.
