He was possibly implying a belief that "large" Money got laid down LATE on Dallas thus some gain of Confidence (increased EV) on (earlier made bets of) Dallas -1.5. To conclude that was "Smart Money" jumping on Dallas at the worst line available all week? As he seems to with: "line got very strong on the cowboys late".....and see Enthusiasm from Sharps to take the plunge at -2/-2.5 on a game who's Total had been seen to go from O/U 35.5 down to 34.5?!!?.....If he is watching The Money i'd be interested to know what resources he's using to accomplish that.
Chasing late steam and reading (basically insignificant) line movements on an NFLx game. Hahahahahahahaha
Bottom line is Dallas was lucky to get the push.
