BYU fans have a long and distinguished history if turning on their players.
Steve Linsley was my neighbor growing up.
When Steve was the QB he was doing his level best at everything he did, and on top of it his amazing dad was losing his battle with cancer. He would make amazing plays, but as soon as threw a bad pass he would get booed and peopke would throw things on the field. Fans in the stands would say horrible things to his mother. The fans were just horrible to him and made his life hell on and off the field.
Unfortunately the same might happen to Taysom. He will lose a game or three, the boo-birds will outnumber the ‘he jumped a Texas defender!’ fans, and he will begin to regret leaving Stanford to go back to that retched cesspool in Provo.
