like i said the only benefit of getting your ST to 172% is that it puts him high at a young age. if you only maintain him to 140% his career will defo be shortened by 6 seasons as once they reach 24 yrs old and older they become harder to train. you can't have it both ways. it's very beneficial to maintain your attackers to end the season on 180% maxed out. guarantees he'll last til he's 33/34 if you maintain him from 160 to 180% every season and that is easily achievable with special sponsor awards, no greenpacks needed
