Keep in mind that FG, FGA, and FG% includes 3 pt. shots. I subtracted the 3 pt shots made and attempted from the totals and this is what I got:
Marvin
08-09 230 made 467 attempted = .49250 2 pt.%
09-10 262 made 532 attempted = .49248
Josh
08-09 392 made 762 attempted = .514
09-10 504 made 999 attempted = .508
Al
08-09 312 made 593 attempted = .526
09-10 466 made 846 attempted = .552
Observations:
Marvin has been consistent over the last two seasons, that is the reason I went to 5 digits on his percentage.
Josh has actually regressed slightly.
Only 1.6% separated Marvin and Josh last season.
