Every Wednesday, Pregame Pro Vegas Runner and Host Gill Alexander get together without any preconceived notion of what they're going to talk about, and seemingly every week, betting gems are revealed.  Today, in addition to delving into VR's Value Top 10 and interpreting tweets about what bettors' expectations shouldn't include when purchasing line services, the exchange highlights the unique enhanced value of cross-sport parlays this time of year and the math behind why laying big money shouldn't always scare one away, including on a game tonight.  Free NHL, MLB, and NBA picks are included, on Wednesday's Betting Dork (April 20, 2011).
