I'm not one to give advice unless it has to do with sex, money, power, music, art, and sports. However, people really should resist the temptation to compare Cassel with other professional quarterbacks. He wasn't even good enough to start in college. He is a level 4 sack-taking, interception-throwing, dinking, dunking doofus who does not belong in the league. Period.
He has no upside and his downside is lower than that belonging to the ass-end of a terrified, trembling, and terror-stricken baby hedgehog taking cover in the tiny, little burrow he dug deep in the sand.
He makes everyone around him worse ... if, that is, he doesn't send them to IR first.
He epitomizes incompetence and exemplifies ineptitude. He is the antithesis of all things good and right and nice and barely qualifies as human given that his brain function scarcely exceeds that of a fossilized, squashed protozoan.
So, no ... he should not be mentioned in the same breath as Alex Smith.
