Everyone looks good on a youtube video. The guy looks like a man among boys. What would he look like versus SEC or Big 12 competition? That's what's so difficult to ascertain.
The Texans took a smaller college prospect a couple of drafts ago. I'd hope they would go with a more proven player that has competed against the best college has to offer. This guy is likely a long term project and the Texans need to see results now.
