At the D1-FBS level, it should be perfectly acceptable to rip on the "kids." Football at this level is a major revenue producer for the schools and the networks. More people attend big time college football games than they do NFL games, and it's not even close. If you expect to play at this level, you better be able to handle the pressure, and the harsh criticism if you fail, and Ellestad is clearly a failure as the Gopher kicker.
If you want to pretend this is all about the love of sportsmanship and rah rah, go watch a D3 game. This is a big time sport with the pressures that go along with it.
