While many sports fans gear up for this year's March Madness, others are turning to a stunning and surprising NFL offseason. With the free agency picks out of the way, the 2015 NFL Mock Draft is looking to be a good one with the top five spots anchored and not likely to change.

To no one's surprise, Jameis Winston still holds the number one spot. He would be drafted to the Tampa Bay Buccaneers as their lead quarterback. The team is looking at an April private workout to confirm their pick.

Defensive tackle Leonard Williams from USC will most likely sign with the Tennessee Titans. In months past, Williams has expressed his love for the team and is looking forward to the likely chance of playing with them.

Dante Fowler is looking to be the top choice as a defensive end for the Jacksonville Jaguars. The player has had a lot of teams approach him in the free agency and while the team has a lot of potential players, Fowler would be the best choice.

The Oakland Raiders are looking to draft Amari Cooper from Alabama as their wide receiver. Not much is said about the pick since it seems to be the most obvious and best choice for both Cooper and the team.

Washington is in need for a new linebacker. The team has already picked out a lot of new players and Randy Gregory from Nebraska could be their crowning jewel in the draft.

For those that don't know the free agency is coming to a close this week. SB Nation reports that some of the best contracts handed out so far are Jabaal Sheard for the New England Patriots, Bryan Bulaga for the Green Bay Packers, Nick Fairley for the St. Louis Rams, Stephen Paea for Washington and Rahim Moore for the Houston Texans.

The 2015 NFL Draft begins on Thursday, April 30 and ends on Saturday, May 2.
