Brady, unfortunately, could not play last season due to a knee injury in the first quarter of his first game last season.
This preseason, Brady would like to play in the preseason games, but head coach Bill Belichick has not yet decided if he will allow the signal-caller play. People are agreeing that Brady, a big-time star over his career, should play.
Most people agree to make a good quarterback he needs to be aware, accurate, and alert on the play. This generally requires preseason play to sharpen his timing.
Tom Brady two seasons ago performed, as most observers agree, to max of his abilities and smashed records left and right. He should go to the max and try to play the same way he did two seasons ago, focusing on getting into a rhythm and finding the weaknesses of each defense.
He should also watch out for pass rushers due to last season's injury; he simply cannot afford another injury to his knee. But it's not all up to Tom Brady. It's also everyone else on the team (especially the offensive line) to perform their best to make a successful season.
