There is still a part of me that thinks the 2016 season ends differently had Jerry Jones allowed Garrett to put Romo back in as QB1. He was playing the best ball of his career from 2014 until retirement. Injuries would always have been an issue. But, I think Dallas should have let him roll once he got healthy that season.
If he came out rusty or just didn't have "it", you knew that the rookie was very capable of winning games and could replace him. If he was 2014 Romo with that young version of Zeke, Dallas would have been in a NFC Championship game at minimum IMHO.
Can't turn back the hands of time. But, man I wonder about 2016.
