McGloin completed 5 of his 11 passing attempts for 41 yards and a pair of touchdowns in Friday's preseason win over the Cardinals.
Although McGloin averaged just 3.7 yards per attempt, he led a pair of touchdown-scoring drives that finished with a 19-yard strike to Clive Walford and a short score to Andre Holmes, both in the first quarter. McGloin will have to duke it out with fourth-round pick Connor Cook for the top backup job heading into the regular season, but Friday's performance certainly didn't hurt his standing in the competition.
