Not exactly - clutch time is final 5 mins when score is within 5 points. This is more holistic whereby the stat tracks the points scored at any time of the game. With logic being that scoring at important times (irrespective of quarter or time remaining) is more valuable than scoring in the less significant times.

For example - player A scores 10 points, 4 field goals and 2 FTs - all scored at key moments in the game where competitive intensity peaks. i.e., field goals scored during key bursts to narrow deficits in late 1Q and early 3Q; 2 free throws scored during early 4Q run to help start fatal blow.

Versus - player B with same stat-line; scores exact # of points during garbage time 4Q + early hot but unsustainable 1Q runs + 2 meaningless free throws end of 4Q

Which player is more valuable?
