If you wanted to look on the bright side then I guess you could say that Tony Romo got out of football alive. That may sound pretty grim for someone as talented as he is/was, but - when it comes to how he's viewed by the vast majority - it's basically his biggest accomplishment.
For Tony Romo the person, this was probably the best decision. I didn't think it was one that he was going to make with the Houston Texans needing a competent QB more than Brock Osweiler needs therapy after completely torpedoing their season so badly that he got traded for literally less than nothing, but that's neither here nor there. There's nothing to suggest he can withstand the rigors of an entire NFL season, and it's long been thought that he had the presence of someone that could be quite successful in the booth. By going into broadcasting now he can continue to rack in paychecks without needing a new hip by the age of 40 and a cane permanently affixed to his hand by the age 42. The value of not having the body of a senior citizen before experiencing his mid-life crisis (that's undoubtedly on the horizon after having to force a smile through the entirety of Dak Prescott's dream season) can't be overstated.
For Tony Romo the legacy, however, this will be final stamp of undeserved disapproval. The last two years he's has spent carrying a cast or a clipboard will unfortunately make people forget just how good he was before his story became nothing more than what you read on the injury report. Somehow, the 4 year period in which Tony Romo threw for 124 touchdowns and only 48 interceptions while coming a Dean Blandino "catch by every standard but the NFL's" special away from a winnable NFC Championship game will get glossed over in favor of a couple untimely 4th quarter interceptions. Dallas' historically bad defenses will get a pass, because the gun slinger that saved them from complete irrelevance will unquestionably take that burden. Upper echelon starting quarterbacks are few and far between, and this particular one is going to have his otherwise great career defined by a play that didn't even come while he was playing fucking quarterback.
I, for one, feel bad for Tony Romo. Not just because the last time he stepped in front of microphone he looked like he needed a handle of un-distilled bourbon while being forced into conceding his job to a rookie. I feel bad for him because the next time he gets behind a microphone all that he managed to accomplish under center will be revisionist history to those that continue to harp on a fateful botched snap of an extra point in a playoff game. I don't say "poor guy" because he never caught a break at the right time. I say it because all you have to do is take a look at his x-rays to know that he got all the breaks at the wrong time. Maybe that changes in the future, but I wouldn't count on it...
