Everybody knows Cam'ron played a little ball in high school.

But he wants to make sure we know just how good he was.

In a series of Instagram posts, Cam claimed he lit up Stephon Marbury, Rafer Alston and Kareem "The Best Kept Secret" Reid during his young Harlem years, and also mentioned that God Shamgod was there to see it.

Every nigga I gave the business to in HS.. Except #Shamgod lol.. ask'm

Marbury and Reid denied Cam's account, and Killa was a good enough sport to post their objections.

So my former opponents are denying me my high school legacy @starburymarbury we knocked u out the playoffs in the semi_finals to go to the chip in 92' (I'm lying?) I had 27.. U had about 12 and da L, and the countless times in laguardia house I scrapped u. @best_kept_12 I gave u 50 points in Forrest, u always talking bout u had 50 something.. U had about 40.. And u was ringing!! Skip (rafer) was on my team in laguardia house (tournament) and was a lil salty when I got MVP.. Over him.. Y'all all went pro.. Let me live .. Thx @godshammgod12 #YallWasThere lol
