Gabbert showed that he is a Back-up QB. He will never amount to more. And yes our Coaching isn't good, our O-line is terrible, our WR are dropping balls left and right and our D isn't adopting fast or playing great. And the ST is one of the worst units year in and year out under this coach/regime.
So yes, we lost because of many things, but overall, now the season is over and in the last 2 games we should look at young players and asetts that we have or don't.
Maybe we have some luck and get the chance to draft the QBoF this offseason, but we will see.
