Hate to let the facts get in the way of a good rant, but the box score shows a MUCH different story than what you just presented.

1. One starter had 21 minutes. The rest played fewer than 20 (ie less than half the game). If my addition was correct, the bench played 111 minutes compared to 89 for the starters.
2. We played 13 total players which was probably everyone on the roster that wasn't redshirting that year. Pretty sure that Eifert and Toyra were both walk-ons that year.
I can't dispute that you may have been sitting next to a couple of jackasses. We certainly have some just like pretty much every fan base. I deal with them from time to time myself. I can offer you my apologies for that but that doesn't make it right.
I just want to state the facts about our use of players that game. Coach Painter is fairly well respected in the coaching community and I can't recall a time where he did something like you described.
