The 2015 NFL Draft was headlined by Marcus Mariota and Jameis Winston, but neither guy has quite lived up to the expectations of going 1-2. It's always easier to look back at a draft and see where players go wrong, but what would a perfect draft have looked like?

Let's redraft the top 10 of the 2015 NFL Draft.

1. Tampa Bay Buccaneers

Original Pick: Jameis Winston

New Pick: Leonard Williams

The Tampa Bay Buccaneers needed a quarterback heading into the 2015 draft, but this class has been terrible. Outside of Jameis Winston and Marcus Mariota, there has been no one that has found success.

Leonard Williams has been a star for the New York Jets on the defensive line, something the Buccaneers could have really used. The Bucs defense would look a whole lot different with Williams on their squad.

2. Tennessee Titans

Original Pick: Marcus Mariota

New Pick: Amari Cooper

The Tennessee Titans needed a quarterback and wide receiver heading into the draft. They struck out on Mariota and wide receiver Dorial Green-Beckham with their second-round pick.

Mariota didn't pan out for the Titans, but Amari Cooper would have been a game-changer for the offense. The quarterback issue wouldn't have been fixed, but it didn't matter what they did, as they weren't finding the answer for that in the draft class.

3. Jacksonville Jaguars

Danielle Hunter, Vikings

Original Pick: Donte Fowler

New Pick: Danielle Hunter

Considering how the Titans and Bucs did with the first two selections, the Jacksonville Jaguars selection of Donte Fowler wasn't terrible, but he went too high.

Danielle Hunter originally went 88th overall to the Minnesota Vikings, but with this redraft he moves up to number three to the Jaguars. The Jaguars' defense could have been changed drastically with the selection of Hunter.

In 78 career games, Hunter has had 54.5 sacks, which is even more impressive considering his first couple of years with the Vikings he didn't play starter snaps.

4. Oakland Raiders

Original Pick: Amari Cooper

New Pick: Stefon Diggs

Amari Cooper would have still been a great pick for the Oakland Raiders at number four, but he is already off the board, so the Raiders turn their attention to the second-best wideout in the class, Stefon Diggs. Diggs was selected by the Vikings in the fifth round, becoming one of the best wideouts in the NFL.

Each of the last two seasons, Diggs has had at least 1,000 yards receiving and six touchdowns.

5. Washington Redskins

Original Pick: Brandon Scherff

New Pick: Frank Clark

Frank Clark was originally selected in the second round of the NFL Draft by the Seattle Seahawks, but in this redraft, the Washington Redskins would have taken him. There was nothing wrong with the selection of Bradon Scherff, but Clark would have been too good to pass up.

There were some concerns heading into the draft about his off the field issues, but since entering the NFL that hasn't been an issue. The Redskins needed a star on that side of the ball, and Clark would have been the perfect option.

6. New York Jets

Original Pick: Leonard Williams

New Pick: Landon Collins

Secondary pieces are always important for any team and with Leonard Williams off the board, the New York Jets would be looking to improve their secondary.

Collins could play either safety position for the Jets, and in a division with Tom Brady, makes the safety even more important. Collins would have been a perfect fit for the Giants.

7. Chicago Bears

Original Pick: Kevin White

New Pick: Marcus Peters

There were plenty of busts to come from this draft class, but Kevin White tops the list. He couldn't stay healthy which kept him off the field, and really made the Bears regret the pick.

Marcus Peters has bounced around since coming into the league, but he would have been a perfect plug and play guy for the Bears. The Bears desperately needed cornerback help heading into that draft, but instead decided to go wide receiver.

If they could have seen the future, Peters would have been their guy.

8. Atlanta Falcons

Grady Jarrett, Falcons
CP

Original Pick: Vic Beasley

New Pick: Grady Jarrett

The Atlanta Falcons first-round selection of Vic Beasley was fine, but doing it all over again they would select Grady Jarrett, who they selected in the fifth round of the NFL Draft.

Jarrett was considered a project coming into the NFL, but now he should be considered is a first-round talent. He has been a difference-maker for the Falcons, and they would have selected him eighth overall.

9. New York Giants

Original Pick: Ereck Flowers

New Pick: Brandon Scherff

The New York Giants knew they needed offensive line help, but they made the wrong selection with Ereck Flowers. Scherff was already gone when the Giants made their selection, but in this redraft, the Giants get their shot at him.

Scherff would have been a game-changer for the Giants and would have helped keep Eli Manning upright. The last few years of Manning's career would have been different with Scherff protecting him.

10. St. Louis Rams

Original Pick: Todd Gurley

New Pick: Melvin Gordon

Todd Gurley was a standout early in his NFL career, but his knees are a real problem, something that would have caused him to fall in the redraft.

David Johnson was an option here, but he also has fallen off the last couple of years. Melvin Gordon was originally selected 15th overall, but in the redraft, he would be on the St. Louis Rams.

Gordon has rushed for 4,240 yards and 36 touchdowns in his career.
