Matt Schaub is a 33-year-old quarterback coming off a train wreck of a season, but the early returns out of Oakland are positive.
McDonald cited a two-minute scoring drive on Wednesday that saw Schaub execute a patient 10-play drive with a collage of short passes and clock-chewing completions capped by a touchdown toss to Denarius Moore in the back of the end zone.
"He's been very impressive, completing a lot of passes compared to what we were last year," wideout Rod Streater told reporters. "It's looking way better. His two-minute drive ended with a touchdown so I think we're way ahead of where we were last year."
Schaub is a short-term patch for a team eternally on the hunt for its savior under center. If he can keep the mistakes down, he'll enter the season as Oakland's starter and serve as the classic "bridge quarterback" to Derek Carr, who reigned as the top passer on the team's draft board and already has the confidence of Raiders heavies.
