I agree that Knell isn't likely to get pushed out of the rotation easily, but it really depends on how a lot of things shake out. If Bosko looks great, maybe that pushes Kanon to the 3 and less minutes for Knell. Same thing with Mag (although he's not a danger of taking any minutes from anyone at the moment). Baker could also easily steal minutes with his ability to create off the bench. I don't think Knell will be losing any minutes though, largely because I don't think Mag or Crawford are going to justify rotation spots.
My guess is the rotation going into B12 play will be Demin, Hall, Saunders, Catchings, Keba, Fouss, Bosko, Baker, Knell.
