I thought you were questioning what the probable cause was for giving him the field sobriety test.
Ehhh, bending over backward to be fair, I suppose you could call it "straddling" if he pulled out as if to pass, realized the coast was not clear, and got back in your lane. It could also be driving in the middle of two lanes rather than picking a lane and sticking to it.
Unlike a trial on HLN, prior bad acts do come into play when you're talking about the privilege of playing pro ball. So does timing. Sorry, it's not just, but it's real.
I also agree with Clare that Dennard will likely end up on another roster if he's cut, and the team will be in worse shape.
But if they cut him it will be to make a show of cleaning up the joint, not to dispense perfect justice or maximize the chances of winning. It would be a brand-protection move, to be really fancy about it, or it could be a "d%#*!@t I didn't get into the NFL to be the jail team" sentiment on Kraft's part.
I could see him personally doing an "enough is enough" move and putting everybody on notice.
