Updated from Feb. 1 with additional Super Bowl prop bets.BOSTON ( TheStreet) -- With Super Bowl XLV five days away, experts at outplacement firm Challenger, Gray & Christmas suggest there will be a drain in worker productivity leading up to the big game. I couldn't be more thrilled if this article will contribute to that slacking off. I had my second perfect week of the playoffs with correct picks against the spread for the AFC and NFC championship games on Jan. 23. My playoff record against the spread is 8-2, which puts my overall record for this season at 50-44, with one tie. My success rate is 52.6%, shy of the magical 53% threshold. A bettor typically needs to win 53% of his or her bets in order to profit, based on the idea that you have to wager 110 units in order to win 100 units.
