Profar's career minor league OBP/SLG/OPS is 367/449/816, despite a 323/473/696 slash as a 17 year old rookie in 288 PAs in low A.
Cozart's minor league slash is 332/421/753 after 665 PAs in low A through his age 22 season.
367 career OBP, primarily accumulating data between the ages of 17-19? Profar can barely improve on a 234 BA as a 20 year old and be light years ahead of Cozart. His OBP was already .034 higher and the power will come.
