I am not even a Pac apologist as many *******s have deep hatred for me due to my early posts. I think one logical reason why his KO percentage increased in his later fights was that many of his early fights were only 4 RDS, 6 RDS, 8 RDS, and 10RDS. So when the number of RDS increased there is a greater possibility of either KO or TKO. You are going by the first 25 fights. Alteast half of them were sanctioned for 10 RDS or less; and maybe one third for 8 rds or less. Remember, alot of pac's fights were late rd stoppages as Morales 2, Solis, Cotto, Hussein, and Barrera. If he had them early in his career they would have gone to decision.
