Sam didn’t serve any purpose. He washed out. They still haven’t had an out gay player play a single down in an NFL game that counts.
Pretty much every player that was not good at his job got the same “assault” Tebow got. Heck once again we go to the very example you brought up: Vinnie Interceptiverdie, a Christian, and just look at that nickname.
Not a few dropped balls OVER 50% OF HIS PASSES hit the grass. He stinks. Kyle Orton’s completion percentage with that EXACT SAME o-line and receivers was 14 full percentage points higher, and he got cut. Nothing odd about it. Tebow is not a good QB, and that’s what happens to players that aren’t good.
Hard to call all the advance acceptance of gays in pro sports ‘no purpose doncha think?
