Your explanation is way more respect than he deserves as a response.
You are well respected around Texans Talk for many, many reasons. Nobody but a troll or a noob would question it, and that dude ain't new around here.
What Manziel did at A&M is irrelevant to the NFL. No pro football player gives a crap what someone accomplished in college. Some of the greatest college players have turned into busts at the pro level.
Manziel has floated through his football career without learning some basic fundamentals of his position. I see intermediate school QBs learning playbooks, check downs, route trees, and pre-snap reads. Manziel reminds me a lot of VY in that both were coddled through school ball and allowed to win with their athleticism and throwing air balls against lesser talent. Now at the pro level, their lack of sound fundamental lessons at early ages reveals itself. And since they never had to be accountable at younger age, their immaturity reveals itself in a myriad of ways.
Manziel decided to party with Bieber and a bunch of other vapid celebrities instead of putting in his time in the off-season classroom. Carrying around a playbook means absolutely nothing when you are not actually learning it.
And now the truth comes out that he has been unable to learn the playbook, and the sad part is that he's such a narcissist that he appears unfazed that his teammates have to put training wheels on him in the huddle. Most players with a pro mentality would be ashamed and embarrassed at such a story. But not Manziel, which says more about him than any gesture he makes during a game.
