The D-Morn News College Blog analyzed Acie's last 5 min v previous 35 min in each Big-12 game:

Team: Last 5, First 35
Baylor: 7 (2 of 4), 13 (5 of 12)
Colorado: 10 (2 of 3), 11 (4 of 8)
Oklahoma State: 11 (3 of 4) ,5 points (2 of 4)
Texas Tech: 7 (2 of 4), 19 (7 of 11)
Oklahoma: 12 (2 of 2), 7 (3 of 11)

Which give us an average of 9.4 points at 70.6% in the last 5 min and 11 points at 45.7%. Not that surprising. I would love to see the comparisons between his offensive ratings in those two time periods. Maybe I am just dorky enough to figure that out. I will have to fight a decent amount of laziness.

Side node, I plan on referring to the stats on Ken Pomperoy's site much more often. He maintains the stats for all D1 teams using formulas that remove the pace of the game (faster pace means more shot not a better offensive team). Which is very cool. Plus Texas A&M is high on the defensive stats.
