I do think that this abbreviated season -- where DRose has missed 10 games -- has affected his output in the clutch. Just last week (while I was thinking about writing this post) I took a look at his clutch numbers (via NBA Stats Cube):
Comparing with the 2012 image from above, we see an increase in his mid-range jumper (C) and restricted area (A). Is Rose moving back towards the mean? Possibly.
More importantly, who knew making free throws to win Big Macs was such a big deal?
