...Even if the Cowboys did take a quarterback, the reality is that Romo's not going anywhere for a while: his contract is unmoveable, either via trade, release, or retirement. Thanks to past contractual missteps and desperate maneuverings to clear out cap space, the Cowboys have needed to restructure Romo's deal twice to convert his base salary into signing bonuses, pushing the cap hit for those deals into the future. That leaves Romo with massive cap hits on the Dallas roster, regardless of whether the Cowboys keep him or get rid of him:
CAP-HIT-ROMO ONROSTER
ROMO/TRADED/RELEASED/RETIRED/
ROMO RELEASED ASPOST-JUNE 1 CUT
2016/$20.8m/$31.9m/$12.3m
2017/$24.7m/$19.6m/$10.7m
2018/$25.2m/$8.9m/$5.7m
If the Cowboys cut Romo as a post-June 1 release, they would absorb the remaining dead money on their cap the following year; in other words, if the Cowboys cut Romo as a post-June 1 release before the 2017 season, they would owe $10.7 million on their cap in 2017 and the other $8.9 million in 2018. Dallas already has $146.9 million on their cap in 2017, the second-highest figure in football behind Philadelphia, so leaving even $12.7 million in dead money on their cap would be disastrous.
In reality, the earliest the Cowboys can move on from Romo -- assuming that they don't restructure his deal again -- is 2018. They could turn Romo into the most expensive backup QB in the history of pro football, but that's probably not going to happen, either. So if the Cowboys draft a passer, you have to assume that he'll spend a minimum of two seasons serving as a backup and injury replacement before stepping in as the full-time starter in 2018...
