This is all PR speak after the fact. We have no idea how aggressive he was in going for AB. What we do know is that he was interested and looked into him after knowing AB's derelict history.
I'm not saying that McBeane doesn't value character. All of a players traits are considered, obviously. However, if talent is high and character are low and you need that position, there are tradeoffs you are willing to take.
With that said, I dont think McBeane will look into OBJ, because we are already loaded at WR and there is no need to roll the dice on talent/character.
