To clarify, I don't believe we should risk acquiring all talented players with a propensity for bad behavior. There are certain types who I believe are reparable and others who aren't.
If you consider the players I mentioned in my last article, Andre Smith, Burfict, Dunlap, Pacman, Sims, and Tyrann Mathieu, their issues weren't anything I'd identify as completely deleterious to the team. Poor work ethic, smoking pot, over-aggressiveness on the field, immaturity - none of these are necessarily harmful to others. Smoking pot (though I certainly don't condone it) doesn't really have an effect on anyone else besides their own state of mind and work ethic. Pacman "making it rain" at a strip club, when you consider it, was really more of a bazaar, misaligned form of charity to other random strangers. Burfict's egregious penalties on the field in college are prominently a sign to me that he's overly competitive (is that terrible?). Smith, Dunlap, and Sims' apathy had no significant impact (from what I can ascertain) on the drive of their teammates (who most likely relished it as they competed for their jobs). Fortunately, these players' actions are simply the result of immaturity, which Marvin Lewis (and other leaders on the team) have proven themselves adept at fixing.
Other players, such as Chad Johnson, Terrell Owens, Odel Thurman, Cam Newton, Albert Haynesworth, Jeremy Shockey, Dez Bryant, etc. display more cancerous types of characteristics; selfishness, pugnacity, overwhelming desire for celebrity, arrogance, and disregard towards others (including teammates and coaches). These are issues much harder for Marvin Lewis to address and I don't believe are worth the risk. The guys who display these traits are beyond selfish; they are selfish to the point where they will tear down others to boost themselves.
In summary, I view these feces-smearing receivers as part of the latter category of irreparable behavior (imagine the poor cleaning crew who has to sanitize their mess) and the Honey Badger more along the lines of the former reparable category - though you could probably make the case for him being in this latter category as well. Tyrann Mathieu was addicted to weed. Got it. So were probably a decent portion of other NFL players at one point in their lives. My concern on Mathieu falls more along the lines of his possible avariciousness for being a celebrity. If Marvin has expressed interest in him though, I'm guessing he maybe a risk worth taking.
