Here is BA's 2012 profile for catcher Marcus Greene (FLA, 39th rd):
Green's best asset is his athleticism, but like most of Southern California's prep catchers, he has a long way to go to develop his game. He doesn't block or receive well, though he has the natural agility to improve. Coming off a shoulder injury, Green's throwing was up and down this spring, sometimes flashing plus but usually rating as below-average. His bat is an even bigger question mark. He is a slightly above-average runner. Durability is also a concern with the 5-foot-11, 186-pounder, but his athleticism and signability could get him drafted in the top 15 rounds.
Here is their 2013 profile for comparison (TX, 16th rd):
Greene was a 39th-round pick last year by the Marlins out of a New Mexico high school, but he headed to New Mexico JC and had a productive season, batting .384/.463/.727 with 10 home runs and 16 stolen bases. He has a muscular build at 5-foot-11 and 200 pounds, and thanks to his athleticism and above-average speed he plays center field when he's not catching. He moves well behind the plate, and his above-average arm strength is his best tool. He needs to improve his receiving and blocking, but that shouldn't be a problem because Greene is a hard worker with solid makeup. His swing could use some work. He has raw power potential, but has trouble staying back and rolls balls over. He recognizes breaking balls, but sometimes tries to cheat on fastballs and gets caught out front. Greene is considered signable.
