You'd think a potential season-ending injury to Rob Gronkowski would cast a shadow over anything that happened in Sunday's Patriots-Browns game. You'd think. And then Tom Brady stepped forward. The loss of Gronk -- who was carted off the field in the third quarter with what appears to be a serious leg injury -- may prove to the blow from which the 2013 Patriots can't recover. But on this day, somehow, he became an afterthought, at least for a little while. How, you ask? By Brady leading the Patriots -- who fell behind on the Browns' first possession and trailed every step of the way -- to two touchdowns in the final 64 seconds, erasing a 26-14 deficit and giving them an incredible 27-26 victory over Cleveland.
