Having watched Owens during the season he played in Philly, I have come to the conclusion that he doesn't have that many playing years left. He's so emotionally insecure that he won't be able to handle it when his athletic skills begin to decline. He could never be a #2 receiver. I figure he would then pick up the antics to a level where he'd essentially get himself black-balled by the league (which he very nearly did after his stint here).
Well, there are only so many Don Maynards, Art Monks and Jerry Rices in this world. Not everyone can be one, and T.O. is not immune to that universal truth, either. In that regard, I agree with you vis-a-vis deteriorating skills.
However, there's nothing set in stone that says that someone, if they want it bad enough, can't modify their game so that if they aren't effective in one aspect,they can't be so in another, if the argument is that Owens is not a #1 or 2 receiver. Whether Owens can evolve his game from "deep threat" to "possession" receiver is open to question, but his evident skills are not. I think he could easily make the adjustment if he were motivated to do so, and his ego would let him make that adjustment.
Perhaps that is the root of his problem: that he "needs" to be "The Man", and he obviously isn't in Dallas. He certainly wasn't in Philly.
