This makes it seem like Allen is a lock to Win at home vs Avs. Nothing could be further from the truth. Sure, Allen has been on a bit of a roll lately, but the Blues are ranked 17th at home in GPP with the Avs ranking 2nd on the road. That scares me no matter who is in net against the Avs.
I would stream Grubs over Allen for the W, 3-4 GAA if you can absorb it and keep Allen on your bench for this matchup.
