To get into all that your talking University Level Post Grad Thesis.
Some QB's just from a standpoint of observing them in certain situations may get the 'he's a choker' label.
This Super Bowl game was set for what any fan might hope for. For those fans it was perfect. For someone to win the other must lose.
The team and QB with the ball last leads his team in a drive and is a key ingredient in deciding the outcome.
Depended on that outcome can you declare 'a choke' or a failure to execute?
Russell Wilson gunned a near perfect pass.
Ricardo Lockette nearly got to and his hands on that pass.
New England's DB Malcolm Butler executed a perfect aggressive pursuit to get to the ball and managed to pick it.
No one fumbled the ball away or we didn't see Russell Wilson mishandle the snap or otherwise fail to get a pass off. He certainly didn't ....as some silly fans for whatever agenda might desire to paint it...choke.
After the play is called it was as we all saw it. A tremendous defensive play by an inexperienced defensive back. That man was Tom Brady and Bill Belichicks HERO for that Super Bowl win.
