Walsh is just the most obvious practitioner of the "puke hurling" that KK employ.
Overly physical with opponents hurleys being grabbed to ensure they don't break from the tackle being the one tactic they employ again and again.
They get away with it because refs like Barry Kelly seem to view this as not being a foul.
Like Ulster football teams, they surround the man on the ball with three or four markers, with the one on the refs blind side doing the dodgy pulling and grabbing.
Kelly in particular is a sucker for this and invariably penalises the fouled player for overcarrying.
