You haven't been paying attention.
Says Carter, “The number one reason why it was once so hard was bump and run. Typically in college you have one good cover guy and he’s not going to cover you all over the field so you’re going up against the second- and third-best corner. When you got to the pros, guys were bigger and faster and hanging all over you. Now, when you take away that physical contact, it helps the learning curve for a receiver. It’s a lot easier for me to teach a receiver to get down the field because a guy can’t hit him after five yards.”
The stats bear out the theory. According to statistics compiled by Pro-Football-Research.Com, the 2009 season saw a dramatic rise in rookie receiver production. From the 475 receptions on 817 targets for 5,735 yards and 23 TDs that rookies combined for in 2008, the number went up to 658 catches on 1,084 targets for 8,775 yards and 53 TDs by rookies the following year.
Toomer thinks the numbers will continue to trend upward. So does Brandt.
“You can’t believe what’s going on now,” Brandt says. “In high school football here in Texas, I would imagine 95% of the teams throw the football more than they run it, and I think it’s that way in most parts of the country. It’s nothing to see a team pass for over 400 yards in a high school game here in Texas and those are 48-minute games.
“But the biggest thing is if school’s out on the 31st of May, 7-on-7 leagues start on June 3,” Brandt added. “It’s the darnedest thing. They play all summer long, they travel, it’s like AAU basketball. They’re learning how to run routes, they’re learning how to do it against press coverage, there are just so many things they learn that they never did before.”
