We parlay five underdogs together - which we also bet against the spread - in 10 different three-team parlays. That's better than nothing, but the whole point of using just over a unit to score a big win is catching it on the right week when a fair amount of unforeseen wildness occurs. A Buccaneers- Texans- Titans parlay would net just +120 on a five-team round-robin parlay. The biggest flaw in picking three-to-five upsets in the NFL each week comes during the occasional week when there just aren't any.
