In my opinioin, he should stick to teasers. Sure the parlay payouts are better the probability of hitting a two team parlay is .50 raised to the second=.25 or if you take the compliment of that (1-A) you have a 75% fail rate. No rationale person would take a bet with a 75% probability fail rate. The books will gladly sign you up if you play parlays and even give you friendly treatment (i.e. bonuses, free bets, etc..if you keep playing parlays b/c they know you are going to lose long term). Teasers are still low probability plays, points or not, but you get adjusted lines (i.e a team -6 now becomes a pk em is by far the better proposition).

Best advice--stick to straight betting and try to grind it out.

Again, just my opinion...no real solid empirical evidence here.
