Comeback from behind. There is no time element, nor point differential to be inferred that I have ever heard of understood as a given.
Otherwise, do you suggest putting the other team away in the fourth has criteria?
Dallas is up by 3 and stops the other team, then goes on a long drive to be up by 6 and wins. Does this qualify as putting the other team away?
Or is there some nebulous number in your mind that Dallas should have score several more times to make the game a lopsided affair? Is there something to be considered in the way the Cowboys put the other team away, which might indicate Dallas was the far better team and not just the winner?
As the fourth quarter plays out, and your team is behind by four, yet your defense can't seem to prevent long clock-eating drives from the other team, does the four point differential still rankle you if your team eventually overcomes?
You certainly are entitled to your opinion on what constitutes coming from behind or putting a team away. But in the context of singling out one player in a team sport where ten other players will be involved in the outcome seems more like a grudge match than some edict which embodies a tried and true, generally accepted rule about any sport where one team overcomes a deficit to win in the end.
