Sharp Action

As you could've probably guessed, that line move toward the unpopular side — called reverse line movement — is almost always a sign of sharp action given all else remains equal surrounding the game.

Sports Insights' Bet Signals have confirmed that to be the case in this game, as they've been triggered by two distinct market moves caused by sharp action on Pittsburgh at +157 and +148.

Big Money

As if we needed more signs of sharp action on the underdogs, the bet-vs.-money split is also revealing that bigger bettors — the ones more likely to be sharps — are taking the Pirates.

The 25% backing of Pittsburgh has generated 43% of money to this point.
