Mike Mayock 2015 Mock Draft: Complete Results from NFL Network Draft Guru

NFL Network expert Mike Mayock released his one and only mock draft on Wednesday, little more than 24 hours before the start of the 2015 draft's opening round.

With the importance placed on the quarterback position, it comes as little surprise that Mayock had the Tampa Bay Buccaneers selecting Jameis Winston first overall and Marcus Mariota going to the Tennessee Titans at No. 2 to start.

Here is a complete list of Mayock's mock:

Around The NFL noted how Mayock went back and forth about Mariota's final destination:

Mayock elaborated on why he ultimately stuck with Mariota taking his talents to Tennessee:

In referencing and emphasizing those intangibles Mariota possesses, worth noting is how Mayock has made an effort to not fall into the trap of how highly he rated Johnny Manziel a year ago. Mayock has previously said he "overlooked" certain things about Manziel, mainly his off-field issues, according to Mary Kay Cabot of the Northeast Ohio Media Group.

The reason Winston is a different case with regard to his checkered past is his experience in a pro-style offense at Florida State, whereas Manziel, like Mariota, came from a spread system.

Getting away from the potential difference-makers under center, Mayock seems to think quite highly of the offensive linemen in this class. Numerous playoff-caliber teams from last year create a run of offensive tackles toward the end of the first round in his mock.

There was little surprise to see so many pass-catchers off the board. Mayock's prior analysis of this year's crop of receivers was rather spot on, according to NFL Media's Jeff Darlington:

One most interesting choice Mayock made was Michigan State product Trae Waynes to the Chicago Bears at seventh overall. Greg Gabriel of CSN Chicago disagreed with Mayock's Bears pick:

Wake Forest cornerback Kevin Johnson is the second player at his valuable position off the board for Mayock, projected to go to the Miami Dolphins. Omar Kelly of South Florida's Sun-Sentinel passed along some of Mayock's rationale:

Speed-demon receiver Breshad Perriman goes to Houston opposite DeAndre Hopkins in Mayock's scenario. Perriman's alma mater, UCF, reacted to that selection:

A couple of standout picks include running backs Todd Gurley and Melvin Gordon being chosen inside the top 20 by the San Diego Chargers and Cleveland Browns, respectively.

The Chargers do need a feature back after bidding adieu to former first-round pick Ryan Mathews this offseason. Choosing Gurley would be a risk since he's coming off of a torn ACL, but he has all the makings of an NFL star.

Cleveland has two first-round choices and could opt to bolster the backfield, though it does have two promising young runners in Isaiah Crowell and Terrance West already in the fold.

Two players with transcendent talent but character concerns cap off Mayock's mock.

The New Orleans Saints supply QB Drew Brees with a much-needed weapon on the outside in Dorial Green-Beckham, while the reigning Super Bowl champion New England Patriots add perhaps the most gifted pass-rusher in Nebraska's Randy Gregory.

No one can say for sure what will happen until Thursday's drama unfolds. Green-Beckham and Gregory would be two splash picks to cap off the first day of the draft, and they may find themselves in the perfect situations to succeed.

Tennessee could very well trade out of the second pick, as Mayock had initially thought of doing in the mock. ESPN insider Adam Schefter reported Wednesday that multiple teams have called to gauge what it would take for the Titans to move down.

Mariota and the Titans organization are the most significant factors at the top of the order. All the ramifications at play on that pick in particular figure to make this 2015 draft among the most exciting ever.
