Am I dumb to trade for Alshon?

I’m being offered Alshon Jeffery for LeSean McCoy. I view them kinda similarly, but with Alshon having higher upside any given week.

0.5ppr, 12 team, keeper league and I’m currently 2-4.
Behind my starting RBs I don’t have much depth other than McCoy.

QB - DeShaun Watson, Philip Rivers
RB - Christian McCaffrey, Mark Ingram, LeSean McCoy, Buck Allen, Duke Johnson
WR - AJ Green, Stefon Diggs, Cooper Kupp, Geronimo Allison, Chris Hogan,
TE - OJ Howard, Vance McDonald

Would I be dumb to take this trade?

I wouldn’t say dumb, it’s just your preference. I am in a 12 team league and I personally value RB’s, and after McCoy you are thin. You have a good wr staff when Cooper returns, so I would lean towards no on a trade straight up. Since you were offered this trade, I would try to get more out of it, if you don’t feel comfortable with the current trade. Look at his rb’s and try to swing an additional player. And if he wants an additional player, use Allison.

Losing my RB depth was my main concern with the trade. I tried to counter with McCoy and Vance (he has Uzomah as his TE) for Alshon and Chris Thompson, but he didn’t bite so I’ll probably just stay put.
