If Tootoo was a skill guy who was a Lady Byng candidate and never did anything questionable, I'd probably say benefit of the doubt.
But, this is Tootoo, and this is what he does. Questionable hits (and a lot of them), slew-foots, boarding from behind, etc.
Put an Anaheim #25 sweater on the guy who "steps" on the Detroit guy, and what's the number...5, 10, or more? Put a Toronto #44 sweater (who I cannot stand) on him...bidding starts at 10 games. What if that's Avery putting his foot down? Maybe the rest of the season then? If that's the case for these guys, then why would Tootoo get a free pass, when clearly he's a dirty player? There's two guys who "probably" get a free pass (and they shouldn't). Let's just say both play in the Eastern Conference and leave it at that.
He could have held up and tried to avoid contact and clearly didn't. Rather than stomp on the guy, he did this half-a$$ step-but-not-step. That could have had a potentially deadly result.
