They can change the course of a game, slipping undetected to the back of the end zone for a score. Let them run up the seam and they’ll find a coverage gaffe for a quick first down. Passing game not working? Run it to their side and they’ll clear a nice path for your tailback.
Of course, I’m talking about a big, play-making tight end that can do it all -- block, catch and run.
Some NFL teams have two while others would die for just one, but the supply doesn’t seem to fulfill the demand. That will all change in the 2014 NFL draft, and the Pac-12 will be almost solely responsible.
