Texans Roster ranked 21st by PFF

[HPF Bob]

"The emergence of Nick Martin and Julie’n Davenport could work wonders for this line, but there’s little hope for the status quo from a season ago. Left guard Xavier Sua-Filo looks like a bust at this point after back-to-back seasons as a bottom 20 guard."

We have to see what Martin and Julie'n Fries bring to the table and whether there's still a football player inside David Quessenberry's body. I think they are basing that ranking mostly on Su'a-Filo and Mancz.
