Dang. That'll do it.
Young Romo was goofy and idealistic. Parcells kept warning him darker days were ahead.
Then he got punished by unfortunate gaffes - much of it him, a ton of it on others though - from which I believe he never recovered.
By 2012, when he said he "figured it out", he had convinced himself he was going to win a SB.
Then one day in 2016, it all went away when he got injured and Dak kept winning.
When he conceded the job he said he went to "a dark place". I don't think he's emerged from it the same if at all.
