When it comes to judging the best quarterbacks, they all seem to have at least one deficiency. Whether it’s pocket passers like Tom Brady and Peyton Manning who may not be adept at scrambling, or deadeye accurate ones like Drew Brees and Joe Montana who might lack elite arm strength, or strong-armed throwers like John Elway or Brett Favre who weren’t always the most accurate. For others, the missing ingredient might have been decision-making, poise or leadership. That’s what makes Patrick Mahomes so special. There’s just about nothing he isn’t elite at.
