You can already rule out the Jets and Redskins though:
The Jets don't want him: T.O. to the Jets? NO
The Redskins aren't interested: Skins say no to T.O. speculation
So, who does want him? Here's some more chatter from around the league:
The Broncos might: T.O. + Broncos = Uh-O
The Falcons might: Is it T.O. Time in the ATL?
The recently Torry Holt-less Rams might: The Official Bring T.O to Rams Thread
Vikings fans hope not: Should the Vikings pursue Terrell Owens?
The Ravens -- contenders when he went to Philly -- likely don't: Ravens not expected to pursue T.O.
The 49ers don't ... clearly: Source: 49ers not interested in Owens
The Dolphins probably don't: T.O.? Don't even think about it
The Panthers already have an over-the-hill go-to receiver (sans drama) in Moose Muhammad: Panthers and T.O.? Oh no
The Raiders are a possibility ... but, really anything is a possibility with that franchise: Say no to T.O.
Could he stay in-state with the Texans? Doubtful: Would you want Terrell Owens in the AFC South?
There's even a possibility he could join Randy Moss on the Patriots: The Patriots are in the market for a 3rd receiver ... hmm
Eagles ... no.
