EFG% for 1st 5 years:
Curry: 52.6%
Donovan: 51.2%
Curry's EFG% ever since his first 5 years is an absolutely bonkers 59.7%. The primary reason? He started taking more threes. A lot more threes.
Curry's 3PA per 36 minutes for his first 5 years: 4.7, 4.9, 6.0, 7.2, 7.8
Since then? 8.9, 11.8, 10.8, 11.1, 12.5, 12.7, 13.4, 12.2.
Does Mitchell have a similar jump in him? Sadly, probably not, because he's already been averaging 10.0 3 attempts per game the last two seasons, in which his EFG% jumped from a 50.4% average his 1st 3 years to 52.7% (His first three years he averaged 7.3 3 attempts per game).
