I don't have any problem with Metcalf's analysis of our football team as it relates to our inability to beat elite teams. Fair enough. It doesn't really bother me because that's pretty much true of most programs, including about half of the Big XII quite often. I like our odds against what the Big XII calls "the forgotten five" schools on most years. (I did enjoy the "surprise a good team early in the season" comment, because it's patently IMPOSSIBLE to disprove. BYU plays ALL non-conference foes early in the season, a.k.a. the "good teams," and even the better MWC foes we've beaten were clearly "bad teams" as well.)
I also don't have a problem with his need to slip in some negative history of the church. That's his prerogative and he didn't really state anything that was untrue.
What pisses me off is that apparently, our old WAC/MWC foes hated us because our teams were nothing more than a proselytizing front. Where and when did we ever step over the lines of common decency during sporting events? Our players didn't do religious gestures after scoring points. Our fans didn't comb the bleachers handing out pass-along cards (at least not to my knowledge). Our ADs didn't require that "The Testaments of One Fold and One Shepherd" get played on the Jumbotron before kickoff. Did it piss other MWC fans off THAT much that they have to hear a prayer before a game at LES?
I like BYU generating interest in the church via football, but I've always understood it to be a more indirect thing, like "this team is filled with Mormons, and they play football. See, that's one not-weird thing they do." If you're talking explicit reference to religion and puff pieces during games concerning the religious-oriented good the players do off the field, I would argue that the University of Florida did more for the direct promotion of evangelical Christianity during the Tebow years than BYU has done for Mormonism recently.
Aside from that, this PDF is really not that illuminating. It's just an inbox full of suggestions from unqualified people. Some of the letters later on are just plain dumb in regards to the ideas and suggestions they're floating.
