Quincy Carter game 1 Tampa Bay. He never got a fair shake after that game, and running into addiction problems. Not saying it isn't his fault, but he wasn't even on the roster.
The T.O. popcorn in his face play (many fans still hated him, and wanted no part of him. But we all temporarily loved him as our own after that).
Noah Brown's catch last year.
The game Tony Romo replaced Bledsoe, through the catch. Diminish Romo all you want. He had a pretty nice career, and got robbed of a chance at SB. Classic gas lighting by the refs, league.
Troy Hambrick's no-show to OTA's.
I think when Dak Prescott beat Tom Brady in the playoffs. That at least showed that it takes a team. It's not always about just the quarterback.
When Pollard started and Zeke sat last year.
Zeke's last hike.
Those off the top of my head.
