I have been pushing Q for OG and here is a link you might like to read:
Quessenberry has long arms, left tackle length arms, and knows how to use them. You'll also notice, if you've an eye for it, a wider-than-normal stance, which helps him establish a stable, strong base to help with his leverage. Powerful Brandon Williams? Down. Athletic freak Margus Hunt? Blocked. Violent, physical Datone Jones? Shut down. Watch the practices for that blue helmet on the line and you see him keep at it.
2014 is where Quessenberry should begin to make his impact. If Houston feels he's progressing nicely, I can see them letting 32-year-old Pro Bowl guard Wade Smith's contract expire and penciling in Quessenberry as a starting guard with, presumably, Brandon Brooks. That's what the Texans do on the line: they keep young talent at the ready and move them up the chain. A potential multi-year starter from a sixth round pick? Tremendous value pick that could be the steal of the NFL Draft. Even if Quessenberry remains the top swing reserve lineman, that's still good value.
