I don't know, maybe I'm just dense or something, but when someone says a player has high, high potential, what exactly is meant by that?I've only ever seen recruits with high, average, or low potential. Am I missing something here?

Within the "high" potential (blue numbers), there is what we call "high-low" and "high-high."  A high-low guy will improve usually 20-25 points. But a high-high guy can improve anywhere from 30-60 points.  On my Bridgewater State team, my PG was high-high in perimeter. He was 26 PER when I recruited him and is now 86 in PER midway through his junior year.

In order to tell if a guy is "high-low" or "high-high," you have to get scouting reports.  Here is a link to a google doc that shows what messages mean H-L and which ones mean H-H: http://tinyurl.com/2eljoyu

Duke- this has a section talking about potential.

I don't think there is an actual cap on how many points he'll grow if he's high-high. He can grow more than 60 points though. I think you'll typically find these super high growths in areas like LP and PER.

Thanks guys, these links you've provided, are exactly what I was looking for. Now i should be able to tell the difference between high-low, and high-high prospects.

I think with high-high, you can have unlimited growth only in LP and PER. But all other high-high categories usually cap at around 40 or so.

Not sure about all of the attributes but DEF can be much higher than 40 pts. I got a guy right now who has grown about 40 pts and is still blue.

Stamina can.

His table there will show you the likelihood of stat maximum improvement. I'd vote that the post of the year if they had that award.
