When Quentin and Conor Jackson were both in the Arizona system, there were a lot of comparisons.
They both played in the Pac 10, one with Cal and the other with Stanford.
They progressed through the minors together and it was felt that Quentin would hit more HR's, have more SB's and a lower BA and the OBP would be the the same as Jackson's, since Quentin will league the league in HBP.
Quentin, then encountered injury problems and with the huge amount of young outfielders in the AZ system, he was shipped off. Now that it seems his injury problems with the shoulder are behind him, I could see these type numbers.
20-25 HR's. 15 SB's, 80-90 RBI's, .270-.280 BA, .380 OBP
He is also a pretty good defensive outfielder, so they like him out there.
