Anybody can send the text but it wouldn't surprise me if it is from a current player. As I mentioned earlier, you can usually depend on somebody passing on thoughts from closer to the action. If that info is relatively accurate, vs. being a total red herring, then maybe the coach looks a little less crazy.
As for being near the top of conditioning...guess it depends on if that is true, how is that measured, how near to the top was he, did he improve over last year, and if it showed up in practice and games. TO is in pretty good shape, I wouldn't want him on my team though.
I was just trying to point out some 'middle' thoughts and frankly, the "he's crazy" story rarely turns out to be accurate. Students, employees and I guess players can easily pass off the issues as "the teacher hates me", " my boss is crazy" etc...my experience tells me to instantly doubt the maker of such claims.
If he was totally innocent in all of this an assistant coach or captain would have talked to Parker and told him he was off base...that they went to the media with the big sob story tells me they are using that tactic for a reason, if they were right all along it probably wouldn't end up with that article in the press. The idea that a guy with that much experience and that much going on would take the time to persecute some kid, just for kicks, is pretty unlikely, not impossible, but I wouldn't put all my chips on that story.
