Keep Mattison or Pollard for lotto ticket?

[rottytiny 7]

I have Mattison and Pollard on my bench, dont have Elliot or Cook, but drafted them late as potential lotto tickets if theres an injury to Elliot or Cook,  I need to grab a waiver guy because of lineup injuries, but not sure which guy to drop? Tried to trade both to the elliot/cook owners but no dice.

Who you keeping Mattison or Pollard?  Thanks

Yeah, keep Mattison. The Vikes seem to be dead serious about running the ball.

If you can only keep one as a lottery ticket, Mattison.  This is Week 4, which is when Dalvin Cook traditionally goes down for the season.
