Knox won't be playing MLB. Positionally he's struggling at WIL big time and really the only thing he does well is blitz. I think he'll come straight off the roster for Wild as Santos-Knox is something special on teams and getting more and more reps at MIKE in 30 fronts. He's your MLB prospect. I think Wild is out for awhile yet though.
Dressler comes in for Lankford I think. Hard to roster a guy to return kickoffs. It's a luxury. If the other team isn't scoring on you repeatedly kickoffs don't matter. Nichols and Lankford have never got in sync even when he started a few games. The other receivers are just more diverse in what they can do. Flanders too can do a lot on O. They have him all over as a receiver, tight end, backfield and he can block well enough to do all that. Tons of guys can return kickoffs on the roster, Flanders, Fogg, Thorpe, Denmark, Leggett and more. Punts are what we have to worry about more as there aren't many guys who can handle those aside from Fogg.
