taylor is actually at 2630 rushing yards, with 3 games left this season, i don't think its unrealistic to think he could be at 6700 passing and 2800 yards rushing, (187 passing yards and 57 rushing yards per game.) by seasons end.
so a good season 2300 passing and 1200 rushing, would put him at 9000 passing and 4000 rushing. hell, if he finishes this season really strong, he could be at 6800-6900 passing and 2900 rushing by the end of the season, which means a really great, heisman kind of season, like 3100-3200 passing and 1100 rushing, could put him at 10000 passing and 4000 rushing. which is insane!
