Both players are entering critical years and Saturday represented their most extensive playing time of the preseason. It's likely they aren't overly pleased with their performances -- both failed to lead their teams on scoring drives as Kansas City was blanked 24-0 at Miami and the visiting Cardinals beat Oakland by the same score.
Croyle completed 12 of 21 pass for 110 yards and threw one interception. Russell completed his first four passes against Arizona but slowed down. He finished 14 of 28 for 140 yards. He was also picked off once. Russell's 28 passes were by design. He threw a total of 22 passes in the first two preseason games combined.
Neither can do anything about not playing well Saturday night. They are their team's starters and they both need to prepare for the regular season and forget Saturday night as quickly as possible.
It wouldn't be a surprise if both QBs miss their final preseason games this week. Croyle's Chiefs' play at New England on Sept. 7 and Russell's Raiders host Denver on Sept. 8 in Monday Night Football.
By then, they'll be operating with a clean slate.
