When Beane took over, in one of his first interviews he said there is a saying that goes something like: There are "guys that play professional football," and then there are "professional football players"...and he favors the latter.
Dareus needs to decide which camp he wants to be in. He has all the skills to be a world beater in this league. The way his contract is written, as we all know, essentially allows him to fail another drug test and get paid to not play football. Or, he can decide he wants to be a force in the league.
