As a Cook owner, should I trade Montgomery for Mattison?

10 team half ppr. My other RBs are Cooks, Jacobs, D Johnson, and Lindsay. I have a couple of other wrs as good flex options too. I’m just really worried about Cook this season and this has been the best proposal I’ve gotten from the Matti son owner who picked him up super early

You have good RB depth Mattison wont get you more the what Montgomery gives you if theres an injury. The bears schedule is easy this season there’s a good chance they’ll be running the ball for Montgomery

Lindsay is in a timeshare hell get carries, if thats david johnson hes gonna do okay this season. Handcuffing is only needed if you dont have depth behind your runners but if you have the depth you may be giving up more then you gain.

one cavaet to this is if you want to lock up the vikings offense for years to come in case they move on from Dalvin Cooks and just keep mattison then I would do it.
