Locket struggling; Now Antonio Brown?

I have Tyler Locket and Keenan Allen. Locket has been pretty inconsistent and has lost me some games at times. If AB goes to Seattle what do you think will happen to Locket’s production level? My gut tells me it goes way down and I feel like I should try to trade him now, but I dont know what I can get for him coming off two bad games and three good games.
