Biggest surprise: Safety John Busing was a playmaker and a big hitter all preseason, and he came in at a position where the Texans added only a late draft pick, Troy Nolan, who’s on IR. Busing played in 27 games with the Bengals over the last three years, but the little-known undrafted player out of Miami (Ohio) has worked primarily as a special teamer and could be a key teams player for the Texans. Underdog receiver Glenn Martinez also stuck.

No-brainers: With Rex Grossman’s performance in the preseason finale, Dan Orlovsky’s shaky, up-and-down performance through camp and Matt Schaub’s capacity for getting dinged, the Texans are well-served to keep three quarterbacks. Grossman certainly ranks as one of their best 53 right now, and could be better suited to be the backup at the start while the team rebuilds Orlovsky.

What's next: They need veteran cornerback Dunta Robinson to sign his franchise tag and join the team, and if it means negotiating incentives that would free him from the possibility of a second tag next year, they should meet him partway on those. Also, while Antonio Smith will kick inside sometimes, the interior defensive line was not good in the preseason. The team has to at least consider whether the right outsider couldn't rank ahead of Frank Okam or DelJuan Robinson, though the team has invested a lot of time and energy in developing them. And how much does Jeff Zgonina, in his 16th year, have left?
