The question of why Brown chooses to run his team this way is moot. But assuming insanity in Cincinnati (Cinsanity?) really is the goal, there's one obvious obstacle in his way: these players keep getting arrested, suspended, drunk, fat, or in one tragic case dead.
So each and every year the Bengals sign the newest generation of miscreants. I'll go back a couple of years to illustrate:
In 2007 drunkard Odell Thurman and general asshole Shuan Smith (who was brought back to the team for a few games in 2009) left the team. The Bengals went out and got Harvard (freaking Harvard) quarterback Ryan "Crazy Legs" Fitzpatrick. In 2008 the team lost Chris Henry to suspension. They replaced him by drafting DUI machine Jason Shirley, and signing Jordan Palmer, who runs the ridiculously nerdy RunPee. Later in the season they added Cedric "DUI-by-land-or-by-sea" Benson.
