Even if he was eligible, he didn't have a chance in hell at winning the award, not with his current stat profile. This award is nearly always given to off the bench scorers, and Al scored just 8.6 ppg this year (only 6.9 when coming off the bench). It's been 23 years (Aaron McKie in 2001) since the 6MOY winner averaged fewer than 13 ppg, and it's been 29 years since the winner averaged fewer than 10 ppg (Anthony Mason in 1995 was barely under, at 9.9 ppg). Bill Walton is the only 6MOY winner in history to average fewer ppg than Horford did this year (and he still averaged more points off the bench than Al did this year).
Al's strength off the bench is his defense and his ability to fit in seamlessly with the starters, no matter who he was replacing in the starting lineup. Those just aren't attributes that have ever been favored in the voting for this award.
