Ye maby these guys are Ring or MTT specialist.
The tracking sites may be good to check up one players but there database is usually not complete and i whouldnt use them to jugde a players ability exsample of that is my OPR and sharkscope
shows me as a profitable player but not Ferguson,does that mean im better the Ferguson? NO WAY IN HELL! Just shows if had better sucsess at the games the have tracked(and the fact that these sites dont track ring also seriously limits there judging abilitys).
I have no idea if these guys your talking abot are "good player" or not and i dont see any thing wrong with qustioning there abilitys but judging them from tracking sites is unfair.
