Joe Namath and Jim McMahon are two names that come to my head immediately that lived a exorbitant fame lifestyle and still were very successful. We drafted Manziel and we knew who he was, so for any Browns fan who wanted him, or anyone in the FA, to try and change him is just ridiculous. It doesn't matter what color his helmet is, he could play for the Steelers and I still would see no reason why he can't do what he did this past weekend. Heck speaking of the Steelers, Big Ben is no stranger to partying (unfortunately he rapes too) and he has 2 rings under his belt.
From all accounts so far he works his butt off at the training so far. Pettine has gone out of his way to praise him and how humble he really is for the spotlight he gets. From what I hear, Manziel consulted with Pettine before deciding on Vegas and was given his blessing. Maybe perhaps Pettine is smart enough to realize that it's freakin May, he has plenty of time to learn and get better, 3 days off (he still studied) is not a big deal in May.
I wanted Bortles more than anyone personally, but even I cannot sit here and condemn a kid for having a few days of reasonable fun. If he is pulling this in July... then talk to me. We all know if Bortles or pretty much anyone else would have gone to Vegas, nobody would have cared. We don't know what they were doing though because nobody pays attention to them like they do Johnny.
