10 games is what I was hoping for, feels right to me. I do think he was coming in for a big but clean hit, Johnson dodged him at the last second, Kelly instinctively stuck out the elbow trying to catch him. It was dirty and dangerous, you have to just let guys go instead of sticking out your elbow if they dodge you. However, I do think it was a split second, instinctive decision, and not overly malicious, even though it did end up resulting in a very bad hit.
I think that, in general, NHL and AHL suspensions should be much larger than they are. I think the "slap on the wrist" type suspensions, currently 1-2 games, should be more like 5-10, and the really big suspensions, currently 10-20 games, should be more like 40-80. But based on precedence, 10 games seems right here. 10 games is very much on the long side for an AHL/NHL suspension.
