With two rushing TDs already this season, Josh needs only two more to tie OJ Simpson for #2 all-time in Bills rushing TDs.
If my math is right, he is currently #6 among all active NFL players in career rushing TDs, with a shot at finishing the season at #4. (AK will get a bunch more.)
I think this is the current top 6 list:
Derrick Henry - 94
Ezekiel Elliott - 72
Latavius Murray - 59
Alvin Kamara - 58
Melvin Gordon - 56
Josh Allen - 55
