I'm only speaking for Boise State here, but bullshit.
Unless High schools add 4 inches, your claim is ludicrous. 95% of freshman we recruit measure in 1-2 inches and 10-15 pounds less than what the high schools report them as.
Those in the know in the States point out that High schools measure with boots, helmet and pads on, while Boise State measure as they do at the NFL combine.
Do you want to do that this coming season?
We'll check who goes to the combine, accumulate the stats colleges give them, then compare them to what the NFL gives them?
surely its on the internet already somewhere
