The 49ers have a framework in place to trade Aiyuk to the Patriots or Browns if he can agree to a contract with either team, Eric Branch of the San Francisco Chronicle reports.

EDGE Analysis

The two teams reportedly are wiling to meet San Francisco's trade demands but haven't yet met Aiyuk's contract demands. Both agreements presumably need to be hammered out before a trade is completed, with Jets edge rush Haason Reddick providing a cautionary example about trading for a player that's in a contract year and seeking a new deal. Previous reports suggested the 49ers would be more willing to trade Aiyuk if they get a veteran wideout as part of the return, with Mary Kay Cabot of the Cleveland Plain Dealer suggesting Amari Cooper could be involved in any deal with the Browns. Kendrick Bourne (knee) has also been mentioned in relation to a trade with the Patriots, in part because he spent the first four seasons of his career with the 49ers. A trade involving Bourne rather than Cooper presumably would entail far more draft compensation, as the former is still working his way back from the ACL tear he suffered Oct. 29 last season and has had a significantly less impressive career to date. It's also possible these recent reports could inspire another team to up its offer for Aiyuk, although any new suitor would also face the same hurdle of needing to work out a contract with him prior to trading for him. Aiyuk requested a trade in mid-July and has been present at 49ers training camp but is not practicing.
