JaMarcus Russell is terrible, and he should not be starting in the NFL.  Here are a few reason why, let us know if you think of any others.
His passer rating is under 40
His stats in his third year are worse than his stats in his rookie season
His coach is happy when he completes 50% of his passes
Brady Quinn has one less pass attempt than Russell but 14 more completions (31-75 vs 45-74) (Brady Quinn is now benched)
He wears RB elbow pads
