Sloter? lol
He's a FB who played well in preseason. Sat on the practice squad all this time. I think we'll be ok. If Minnesota had 2 FBs on their active roster, somebody needed to be slapped. Can anyone name another FB in the NFL? Yeah, that's what I thought. If that FB gets injured, then you use one of your TEs in that blocking role. OR you sign him from your practice squad, which I'm sure Minnesota would have done if Hammer went down. They aren't hard to find in the FA market, either.
Not saying I don't like the kid's potential, just saying this is really a non-issue.
