Help! New trade proposal

I know on paper this seems like a no brainer. Brown and Smith are the better combo. But both of those guys seem to be cooling off. While Gore may be the best player in the trade.

Gore is going to get alot of touchs with Alex Smith as the QB and TJ is the number one with a not so deep WR group in seattle. Steve Smith shares catches with Manningham and Hakeem as well as Boss the TE and Bradshaw and Jacobs outta the backfield. Brown is iffy I feel like its only a matter of time before he gets hurt running the wildcat. But all in all I see Gore as a twenty point scorer last 8 game of season and TJ averaging 16-20.
