Why are NFL players shrinking?

[Monomach]

In college, tall kids are all over the place. When they leave college, they get shorter. Is this because college conditioning coaches are just that good? Do they have players so the right exercises to make them taller? Why don't NFL teams hire these guys to gain their secrets about coaching players to get tall?

What are colleges doing right? It can't be a coincidence that players are getting smaller as soon as they leave!

A few examples of this strange phenomenon:

-South Carolina's website shows that Alshon Jeffery was 6'4" all through college. By the time of the combine, he lost 1.25 inches! As a Bears fan, I'd like for the team to focus on getting him back up to 6'4" or even like 6'7" if they can.
-Alabama revealed that DJ Fluker was 6'6". By the time the Senior Bowl rolled around, he'd already shrunk by 1.125". In fairness, he could have gained some weight, which would have pulled him closer to the ground.
-A quick perusal of Southeastern Louisiana's site shows that Robert Alford was 6' . At the Senior Bowl, he had gone all the way down to 5'9 7/8"!!! He lost a TON of money! A 6' corner is way more desirable than a shrimp like he is now. He should sue someone for lost wages.
-Quinton Patton? 2 inch loss.
-Kenjon Barner also lost 2 inches!

These are just a few examples. There are literally THOUSANDS more. The NFL really needs to hire some scientists to study how to keep players at their peak height that they grew to in college. Their inaction is ridiculous!

Yeah, I'm a terrible troll.
