honest Q can you even point shave in FCS or whatever
the online/vegas market has such low limits that it probably would not be overly lucrative. for example, if you wanted to bet harvard this week against howard at five major online books and the very few vegas books who will offer lines, i'm guessing you'd struggle to get down more than 3-5k on a particular game. with re-bets (if approved) after line moves, you could probably get it into the very low five figs. a more sophisticated group could probably get at least 20k down on the original number.
so, it's definitely possible. but you'd be a complete idiot to try.
