Field Gulls on Drew Lock

From the article

This might be the most difficult bet to evaluate, largely because of the uncertainty surrounding Drew Lock. However, I don't see much of a middle ground in this matchup. If Lock struggles, Seattle could have a difficult afternoon. Turnovers, particularly interceptions, could give Arizona short fields and keep the Cardinals in a game where they might otherwise struggle to keep pace offensively. On the other hand, Lock could deliver another performance similar to his first meeting against Arizona. If he protects the football, establishes a rhythm with Smith-Njigba and takes advantage of Seattle's improved offensive line, the Seahawks have enough talent to win comfortably and cover the spread.
