Opinion: Why Purdue WR Rondale Moore's dazzling pro day didn't end up boosting his NFL draft stock

Purdue Boilermakers receiver Rondale Moore surprised with just about every measurement during his pro day on Tuesday. Moore's college highlights showed he was an off-the-charts athlete, but few could have expected the showing he had.

He logged an unofficial 4.29-second 40-yard dash to go with a 42.5-inch vertical. His 3-cone times were wild, too. He logged 6.65 to 6.68-second times. Even though he didn't do the bench press, he posted a video of him putting up 24 reps, just in case there were any lingering questions about his athleticism. (There weren't. Have you seen pictures of this dude?)

The only problem? Well, it seems Purdue inflated his height. Moore is actually 5-foot-7 - which is significantly smaller than what teams thought (5-foot-9). That might be a problem.

There is just one NFL receiver listed at 5-foot-7: Dolphins wideout Jakeem Grant. A handful of receivers measure at 5-foot-8, including Cole Beasley and Isaiah McKenzie. Andrew Hawkins, now retired, is one of the few receivers to excel at 5-foot-7.

So there's no doubt that Moore's outstanding athleticism is dazzling. But his height is a problem. Moore was projected to be selected in the second round of many mock drafts before his pro day and now he's probably locked into Day 2 of the NFL draft.

It's weird to think there's a line that says, "YOU MUST BE THIS TALL TO PLAY NFL RECEIVER." But the pre-draft process is an extremely strange, and NFL teams are extremely fickle.
