So he fired a shot at the buzzer and hit someone with it? Yeah, that's... there's no RULE against that, but it's not really okay either- I used to get shots fired at me in net after the buzzer as an 'oops', and it was always cause for shoving and whitewashing. (On one occasion, the buzzer went off, I had enough time to grab a gulp of water and get halfway to the bench, and THEN got hit in the shoulder with a shot, because he 'didn't hear the horn, sorry!'. The short version is that we both were ejected for the discussion that followed. :rolleyes )
There's not much you could do in terms of league discipline- no rules were broken- but I'll bet Watson's happy to have Nashville on the schedule only on rare occasions, because the next game against them is going to require a head on a swivel.
