I am not familiar with him, if you caught him during a hot streak that's great. long term you will lose with anybody from pre game. bottom line is if you are betting 11/10 (regular vig) which you probably are, 52.4% is break even. if you're paying for picks, you have no chance. those guys are throwing darts. if Spartan recently got hot recently, i would fade every one of his next 50 picks i GUARANTEE you come out ahead.
pregame has regularly employed criminals - of late his record monitor Jeff Scott (not his real name) , a convicted pedophile , David Glisan (not his real name) - convicted scammer, the list goes on and on.
Cokin and Shaker are well known long term losers, as is Teddy Covers (not sure if he's still there)
Fezzik , like all of them, pimps records graded with stale lines, uses small sample sizes in record keeping, bets props with tiny limits , chases steam, etc etc. he is truly the king of all the frauds.

i used to read about these guys on a forum and dug in a little bit, it's criminal what they do
