If you really want to be confused and have a scratch-your-head moment, take a look at video highlights on YouTube from Troy Williamson's play at South Carolina. Any NFL scout had more than enough reason to believe he was a dominant football force.
Literally there are plays where he looks three times faster than anyone else on the field. He runs with confidence, power and great downfield vision.
Now, look at his NFL highlights, and you're more likely to find a a healthy amount of "lowlights", including some of the most awkward looking dropped passes you've ever seen.
Go one step further. Remember the reverse he ran for us the other night against Tampa? He looked gangly and scared, even on that little play. And remember his kickoff return? Williamson ran right into a rather nasty tackle and made no attempt to cut and use his speed to the outside.
In conclusion, it's hard to define how drop-offs of this magnitude occur. There's just a natural balance and style in the NFL that is unique and demands something intangible out of a player. A nobody like Jimmy Smith can become our saviour. And a college super-stud can disappear and play as if he never belonged.
It's mind-boggling. And it's got me scratching my head. I'm afraid Mr. Williamson will soon be scratching his yet again too.
