Owen Daniels acknowledged there's a chance he may not be back with the Texans in 2014. "I try not to (think about it)," Daniels said. "I think I'm one of the leaders and one of the staples of this team. If they choose to keep me my last year of my contract, which I hope they do, that's great. I'd like to play here and only wear this uniform. ... The uncertainty is always weird. ... So I'd like to know basically." Daniels is set to count $6.25 million against the cap in the final year of his deal. He's also become increasingly injury-prone at 31 years old. Garrett Graham is headed for free agency. Rookie Ryan Griffin showed he can handle a full-time role as a pass-catching tight end.
