Too bad L.C. doesn't do basketball statistics. I'd like to see a stat with what percent of the time does the team with a "monster dunk" actually win the game. I guess that one is hard because "monster dunk" is a little subjective. In football, I've seen a stat that a team that has a safety scored against them loses the game at something like 65 percent of the time. But, a safety is an objective measure, unlike "monster dunk." But, if L.C. was a basketball fan, I bet he'd figure out a way to come up with this stat!
[For the sarcastic impaired, the above has a modicum of sarcasm laced with a smidgen of reality.]
If we are saying that a dunk is worth more than two points because it is demoralizing I don't know but I don't see any indication there that a safety is. 65% seems reasonable or even kind of low. I mean a safety is only worth 2 and a TD is worth, usually, 7 because it comes paired with an extra point but if you score a TD you give up the ball. If you get a safety you get the ball in good field position so the swing for a safety is close to the same.
Now, it probably is not true that teams that score a TD win 65% of the time because it is a common play. But if you phased it such as teams that score the first TD, or the last TD, or even the 2nd or 3rd TD to single it out as a specific event as a safety usually is then, sure, 65% or more seems reasonable.
I don't know about the dunk but I know how math analysis studies on momentum usually go. Its usually pretty hard to find. I'd bet might find that a dunk is effectively worth slightly more than a typical 2 point basket but not two 2 point baskets.
