2015 Fantasy Football Dynasty Rankings: Rookie Quarterbacks (QBs)

Tampa Bay's Jameis Winston and Tennessee's Marcus Mariota will be linked (and compared) to each other throughout their NFL careers as the top-two selections in the 2015 NFL Draft.

Not only did each of the clubs invest such a high pick in both quarterbacks, but they used many of their other early picks to bolster the talent -- pass catchers and pass protection -- around their new franchise quarterbacks.

Although our dynasty rankings take a long-term view (obviously), we won't have to wait long for the first Winston-Mariota showdown of their careers as Tennessee travels to Tampa Bay in Week 1.

Here are my rookie dynasty rankings for quarterbacks from the 2015 NFL Draft:

1. Marcus Mariota, Tennessee Titans

Described by ESPN's Jon Gruden as a "6-foot-4 Russell Wilson," Mariota possesses all of the physical tools to develop into an elite fantasy quarterback. Naturally, there will be an adjustment period for Mariota, as there is with all rookies, but no other quarterback in this year's class has a ceiling as high with his ability to create outside the pocket. Mariota, who won the 2014 Heisman Trophy, posted a 105:14 TD-to-INT ratio in his career and rushed for 700-plus yards in all three seasons as a starter with a total of 29 touchdowns on the ground.

2. Jameis Winston, Tampa Bay Buccaneers

Despite his past off-the-field concerns, Winston possesses strong on-field intangibles (leadership skills and football intelligence) that you'd want in a franchise quarterback. At the combine, NFL Network's Steve Mariucci described Winston as the "the most astute X's and O's guy that he's ever put on the board." With a strong arm and experience throwing with anticipation in Florida State's offense, Winston will likely make more of a fantasy impact early in his career than Mariota and also possesses a higher floor than Mariota.

3. Bryce Petty, New York Jets

Coming from Baylor's spread offense, there will be a steep learning curve for Petty. With only Geno Smith and Ryan Fitzpatrick ahead of him on the depth chart, however, it wouldn't be a shock if Petty earned some starts as early as 2016. The Jets have a solid trio of receivers in Brandon Marshall, Eric Decker and rookie Devin Smith to help whomever is under center.

4. Brett Hundley, Green Bay Packers

Hundley lacks pocket awareness, but he possesses a strong arm and good mobility to make a fantasy impact if/when he gets on the field in the future. With good health for Aaron Rodgers, however, that future may not begin until after his rookie contract expires. On a positive note, he gets to learn from the NFL's best quarterback and from within one of the league's best organizations.

5. Garrett Grayson, New Orleans Saints

Like with Hundley, Grayson will have an opportunity to learn behind one of the league's best quarterbacks and from one of the league's strongest offensive coaching staffs. Like with Hundley, though, it's certainly possible that Grayson doesn't see the field -- barring injury or kneel downs -- for the entirety of his rookie contract. The Saints used a top-75 pick to make Grayson the third quarterback off the board, which highlights their confidence in him and his potential to take the reigns from Drew Brees at some point down the line.

6. Sean Mannion, St. Louis Rams

Mannion has good size (6-6, 229) and has experience as a four-year starter in Oregon State's pro-style offense. While the team traded for Nick Foles, he's entering the final year of his contract and the Rams used a top-90 pick on Mannion, which indicates that they view him as a potential replacement. That said, Mannion lacks ideal arm talent and may not develop into much more than a solid backup.

7. Brandon Bridge, Dallas Cowboys

Bridge has good size (6-4, 229), decent mobility (4.72 forty) and a cannon for an arm, but he lacks touch and accuracy. Despite playing at a lower level of competition at South Alabama, Bridge completed only 52.1 percent of his pass attempts in 2014. Against his toughest opponent in 2014 (South Carolina), Bridge completed just 2-of-11 passes for 19 yards.
