What, you don't think his little rant was poor sportsmanship?
Not in a way that matters. Aaron Hernandez is "classless", what Sherman did was funny.
Seriously, you Americans are so strange about this stuff sometimes - "running up the score" (an expression that doesn't even exist
in Europe) is bad sportsmanship, the fans making too much noise is an "unfair advantage", but freakishly big men bashing each other's heads and breaking their bones is fine sunday afternoon family entertainment.
