I'm quite disgusted by Marcel's actions over the last year.
IMO, he should either dedicate himself to being the best NFL player possible at his position using his God-given gifts and natural abilities. Or, he should sack up and retire at an early age, because he's going to lose more supporters than win them if he continues with his lack-luster, dilettante approach to the game is clearly a detriment to his growing as a professional.
