I agree that on the whole he's not a troll. Probably an "agitator" is a better word for it. Maybe he sees himself as a Yankees friend of mine from another board has said (and yes, it's ok to have Yankees friends), he's just "keeping us honest". Of course, as I've said in the past, when someone uses "maybe" - as I just did - they're admitting that they don't have firm evidence to back up their position - they're just throwing something against the wall to see if it sticks.
However, IMHO on this particular topic he's either perpetuating the discussion for the sake of perpetuating it or else he can't stand to see someone else have the last word. Most of us here see the video evidence as being pretty clear regarding what Austin did around second base and his charging the mound. Those two things are quite indisputable to any reasonable "hypothetical jury".
The only thing that can be questioned is Kelly's response. IMO in the eyes of baseball people it was a normal - but unsanctioned - response while in the eyes of the "turn the other cheek" folks it's inexcusable.
I can live with that.
