If not for starting only nine games, Marino would have likely taken the top spot. The Dolphins went 7-2 in his nine starts, and Marino made the Pro Bowl after throwing for 2,210 yards and 20 touchdowns in 11 games. Marino went on to win the NFL MVP the following year.

Prescott saved the Cowboys season when Tony Romo got injured. The fourth-round rookie was uber-efficient, completing 67.8 percent of his passes for 3,667 yards and 23/4 TD/INT. He was also a major threat on the round, rushing for 282 yards and six scores in the team's 13-3 regular season.

Wilson wasn't supposed to start in his rookie season after being drafted in the third round but beat out Matt Flynn in the preseason, and the rest is history.

He added 489 yards and four scores on the ground.

The fifth overall pick in the 1969 draft by the Bengals, Cook was terrific in his rookie season. He threw for 1,854 yards and 15 touchdowns in 11 games and rushed for 148 more yards. Unfortunately, a shoulder injury limited Cook to just one more game following his rookie campaign.

Wentz's fast development caused the Eagles to trade Sam Bradford before Week 1 and install the rookie. The Eagles went 7-9 in his rookie season, but Wentz completed more than 62 percent of his passes and threw for 3,782 yards, 16 touchdowns and 14 picks. He added two scores on the ground.

Mariota played only 12 games in his rookie season due to knee issues, but they were 12 productive games. The No. 2 overall pick in the 2015 draft threw for 2,818 yards and had an impressive 19/10 TD/INT, also rushing for 252 yards and two scores.

Despite going 3-13 in his rookie season, Carr was productive in 2014. The second-round pick threw for 3,270 yards and 21 touchdowns to only 12 interceptions.

Batch was a backup for most of his career but had a fine season in 1998 handing the ball off to Barry Sanders in the legendary running back's final year.

Flacco had immediate success with the Ravens, helping lead them to an 11-5 record with 2,971 yards and 14 touchdowns. Of course, he had the help of a great defense.

A 29-year-old rookie and first-round pick in 2012, Weeden threw for 3,385 and 14 touchdowns in his rookie season. That was the good news. The bad news was that the Browns went 5-10, and Weeden threw 17 picks.

A 34-year-old rookie from the CFL, Brock led the Rams to an 11-4 record in 1985. He had 2,658 passing yards and 16 touchdowns, with 13 interceptions, completing nearly 60 percent of his passes. He's now a member of the Canadian Football Hall of Fame.
