Based on their performances in the Green Bay Packers' first preseason game versus the Arizona Cardinals at Lambeau Field, is it any wonder why the team signed veteran Vince Young to compete against the other two backup quarterbacks earlier this week?

In a word, the backup quarterbacks were dreadful in the 17-0 loss to Arizona. Young played the best among them, and he was just signed a few days ago. What does that tell you?

Of the three quarterbacks competing for the primary job of backing up Aaron Rodgers at quarterback, nobody looked worse than incumbent Graham Harrell.

Harrell was 12-of-19 for just 76 yards, plus he was sacked twice, fumbled once and also threw an interception. Harrell had multiple series opportunities (six) in the game, but the best he could do was produce a 45-yard drive.

The two turnovers by Harrell led to touchdowns by the Cardinals.

This is coming off of a very inconsistent and unproductive 2012 preseason mark last year by Harrell. Harrell finally produced in the final preseason game of the year against the Kansas City Chiefs, but he did not look good in the other three exhibition games.

Harrell also had a key appearance in a regular season game, when Rodgers had to leave the game briefly due to getting poked in the eye. Harrell fumbled on a handoff as the Packers were just yards away from the New Orleans Saints goal line.

The Saints went on to score a touchdown after the turnover, and the Packers were fortunate to win that game, 28-27.

After Harrell was given six series to try to move the ball with very little success in Friday night's loss, the Packers surprisingly went to the newly signed Young.

Young was just 1-of-3 passing the ball, but he did produce two first downs, one on his lone completion and another by scrambling for five yards. Not earth-shattering stats, to be sure, but not bad after trying to learn the Mike McCarthy offensive system for just a couple of days.

B.J. Coleman then took over at quarterback and was only 2-of-7 for 15 yards. This was coming off an awful performance in the Family Night scrimmage.

Bottom line, expect Rodgers to get the majority of his preseason action in the third exhibition game versus the Seattle Seahawks at Lambeau Field on August 23. Rodgers will play probably at least half the game.

As for the rest of the preseason action, except a few series to be led by Rodgers, with Harrell, Coleman and Young all splitting time. 

Somebody has to show something.

Harrell looks good in practices and scrimmages versus his own teammates, but he struggles against real competition.

Coleman looked good in the rookie minicamp, which also had second-year players in attendance, but he has been inconsistent and unproductive since then.

Young, meanwhile, has a solid NFL resume and a sparkling college one. In college, he won a national title while he was at Texas.

In the NFL, he was the AP Offensive Rookie of the Year in 2006, plus he has been named to two Pro Bowls. In his career, Young has thrown 46 touchdown passes (versus 51 picks) for 8,964 yards. Young has also rushed for 1,459 yards and 12 touchdowns.

Time will tell how all this plays out and who will become the primary backup to Rodgers, but if I were either Harrell or Coleman, I would be really concerned about my job security.
