Sanbagging seems rampant in no gi grappling, but is concentrated in the novice and beginner divisions. Alot of times folks just dont realize.....IF YOU WRESTLED IN COLLEGE...you are not a beginner, and certainly not a novice. Dont see many baggers in intermediate, folks seem to be honest at that point. Hell I watched a guy win the beginner division at one comp who I know has been training for over 3 years. Pointless to say anything though, then the story about "it wasnt consistent", or "all of it wasnt in a gym" etc. Folks who do this are as said, hurting themselves and sort of completely missing the point of grappling comp (to make your game better) for the lesser issue (winning some trinket).
