Right but apparently it's an NFL rule that you can't have alcohol on team planes(per PFT) and the entire intent of said rule is so you don't have players getting off the plane drunk, and driving.
So if Floyd really got drunk on the plane, to this extent, the Cards are going to be investigated and should be.
I agree Michael Floyd is responsible for his own actions, but to get THAT drunk it's not like he just hid a couple of cans of beer as he got on the plane.
But again I think it's pretty likely he's not telling the truth about where he consumed the alcohol.
Cards would have landed at what, 9-10 PM? He was arrested at 3 am, 6 hours later. I would bet majority of drinks (if not all) were after he landed - probably went straight to Scottsdale from the Training Facility (or wherever they park)
