Toney...JuJu...MVS...Hardman...Moore...Kelce...CEL.
Good luck starting anyone other than Kelce.
I'm gonna be on the other side of this one. I think there is value to be mined here. JuJu feels like the clear #1 WR, he's also got a very different skill set than the other guys, so his role feels safe.
If Toney can get back to where he was for that 2.5 game stretch his rookie year, I could see him making quick work of Moore/Hardman, and being ahead of MVS, who is/has always been 1 dimensional. There is a certainly a possible scenario, where the passing game is Kelce, JuJu, Toney, as the clear top-3 guys, in few weeks once Toney is up to speed.
I don't think they traded a 3 for a depth piece. I also think they have been pretty disappointed by MVS/Hardman/Moore, and none of those guys demand targets. Not saying Toney suddenly becomes a WR2 for fantasy or anything, but he's certainly increased in value with this trade.
