sharps have put a ton of money on mississippi state today is my guess. Craig Stevens, arguably Auburn's best LB, won't play tonight and didn't play against Arkansas State....i'm not sure why the line has moved 4 points in MSU's direction just today. Is this going to be a thing now? Years ago I never heard anybody talk about "going chalk" on their brackets, and then every Tom Dick and Harry was using the phrase. I'd never heard the term "sharps" used before this football preseason and now I'm hearing it all the time. By the way, 2nd google option is SkinHeads Against Racial Prejudice. the term "sharps" isn't a super new thing. it has been around for at least a couple of years now. Professional gamblers, wiseguys are known as "sharps". Amateurs (those who aren't privy to the savvy point of view) are known as 'squares'. Vegas seems to lay out odds in such a way that squares will naturally pick the wrong side of a bet. when things seem too obvious, something probably is amiss. I understand the word isn't new, but people using it in public is. I saw it again last night in a publication that never used it before. As for your last point, not really. The so called sharps bet against each other all the time.
