I think the problem people have isn't that he blew it off, but rather that he couldn't do well on a test that's one of the easiest tests you could possibly take in any profession. This isn't the SAT or even a pop quiz on anything relevant... It's almost infuriatingly simple. If the test was any indication of his intellect, the majority of this board probably was smarter in 6-7th grade than this guy is now and he almost or does have a degree from a major college.
I'm not saying ND players are rocket scientists, either. In my sophomore year stats class, the professor asked the football players in the front row if they knew how combinations/permutations worked. They said no. He gave an example, asking "If the football team has 100 players, how many combinations of 11 players can there be on the field?" and one of them (honest to god) said "100?"... The answer nearly took up the entire chalkboard. We're talking about a few pretty big notches below that on things that happen in everyday life and include no math/science/lingual skills beyond about elementary-school level.
The odds are also staggeringly low that he blew it off and just put in random answers. It's hovering around 1% (50 questions, 5 answers per, 4 correct) unless he just answered the first few answers and stopped, but why would he do that?
If the test doesn't matter, why is it taken at all? It opens these guys up for unwarranted ridicule and makes owners (I'm looking at you, Jerry) look like they don't value the student-athlete approach to college athletics. I'm kind of embarrassed to be a Cowboys fan. Drafting these guys so high up makes it easy for guys to slip through the cracks that can't read, can't write and can be taken advantage of by the league, their friends or crooks that start ponzi schemes. It should be about the players and it's not.
It's just sad on all sides.
