Point 1 - I'll agree with that one. That was a major f up on his part. Whatever, it happened, it was a single time thing.
Point 2 - if he did indeed interfere or influence an investigation, why wasn't he charged with something? How come the prosecution, or the state, or the investigators, go after him or the ones involved? You're reaching here, and you know it. You want to let the legal system run its course when it comes to ISU athletics, or when it proves something nasty is going on in Iowa's, but when it doesn't, you claim to know something that you really don't. The fact that nobody but a few ISU fans made a big deal about KF's involvement in the rape fiasco means one thing - his involvment was limited, and he cooperated to the extent he could.
Point 3 - if Doyle is so incompetent, why have the players not filed lawsuits against him? Again, see point 2. You're making assumptions about a situation you again know nothing about. If he was indeed incompetent, he'd be gone, and he'd be facing charges of some sort. Instead, not one of those 13 players have left the team, all have returned to full health, and none have had any complaints with him.
