Dynasty Trade Help…

I’m in a 14 team, Full PPR, 2 flex dynasty league and got offered the trade below. I’ve been very high on McLaurin but am conflicted with what to do. I think this trade may be too good to pass. The age of both Jones and Allen make me nervous but would be helpful to have another RB with Montgomery out for 5-6 weeks.

Sending:
McLaurin
Tua
2022 First round Rookie Pick

Receiving:
Aaron Jones
Keenan Allen
Baker

Current team
QB Mahomes
QB Tua
RB Montgomery
RB Carson
RB Sanders
RB Patterson
WR Hill
WR AJ Brown
WR McLaurin
WR Cooks
WR Sutton
WR Gage
WR St. Brown
WR Bateman
TE Waller
TE Kmet
