I love the theory that Lew "they don't call him Dollar Bill for nothin" Perkins allowed $3 million in tickets to just slip through the cracks.
Love it.
Exactly... why would Lew "allow" his athletic department to lose money?

Um... pretty sure you are misinterpreting what he's saying. 
"Allowing" something to happen means that you're conscious of the situation. If Lew "allowed" it to happen, he knew about it. Most KU fans are claiming he didn't know about it.

yes, i am aware that KU fans think this. At the risk of speaking for the esteemed michigancat, I believe he was implying that a man highly regarded for his financial acumen (thus the Dollar Bill reference) would actually be far more likely to, in fact, know stuff about money and tickets. That it would be far less likely that he would NOT be conscious of it.
And by the way, as I pointed out earlier — if he by some remote chance he didn't know, that in and of itself is a fireable offense to not be aware of your own senior staff's dealings and the loss of millions of dollars (on top of his prior unawareness of academic fraud and lack of institutional control). For a man lauded for his abilities, he sure seems to "not know" alot of stuff.
