The 2018 Nfl Draft is only a few weeks away and there are NFL teams that have big questions concerning players that are already on their rosters. These questions surround some pretty major stars and their places with their respective teams in the future. These players include names like the Dallas Cowboys' Dez Bryant, New York Giants Odell Beckham Jr. and New England Patriots Tom Brady. Here is a look at the five biggest questions heading into the 2018 NFL Draft.

Dez Bryant, Dallas Cowboys

The biggest question for the Dallas Cowboys this summer was not how to improve their defense (although that is important). The biggest question for the Cowboys was what to do with Dez Bryant [VIDEO].

Dallas signed Dez to a five-year, $70 million deal back in 2015 and he has done nothing to earn it, spending time injured while struggling with any quarterback not named Tony Romo.

The Dallas Cowboys owe Dez Bryant $12.5 million this season, with a cap hit of $16.5 million. There is a good chance the Cowboys could trade Bryant before the draft, or release him after the draft. if Dallas still has Dez on the roster by the 2018 NFL Draft, and they draft a receiver early, the signs are there.

Odell Beckham Jr., New York Giants

Unlike Dez Bryant, Odell Beckham Jr. has earned his contract money. At one time, it seemed like there was no way the Giants would part with Beckham. However, they are now considering trades and want at least two first-round picks for the receiver. Teams like the New England Patriots and Los Angeles Rams have popped up in trade rumors.

If the Giants find a suitor, they will be able to replace Beckham in the 2018 NFL Draft and probably still be able to draft Eli Manning's eventual replacement as well.

Tom Brady, New England Patriots

The New England Patriots made a strange move in 2017. The Pats traded backup quarterback Jimmy Garoppolo to the San Francisco 49ers -- where he became a superstar. That left them starting from scratch with an eventual replacement for Tom Brady, who is over 40. The Patriots were in the Super Bowl last year, so their best draft pick is not high. Expect them to draft a quarterback -- possibly in the second round -- to groom as Brady's replacement. Mason Rudolph maybe?

Ben Roethlisberger, Pittsburgh Steelers

Every offseason in the NFL for the past few years, Ben Roethlisberger contemplates retirement. Much like the New England Patriots, the Pittsburgh Steelers need to figure out their future at quarterback and Landry Jones isn't it. The problem is that the Steelers also don't have a good first round pick.

The best bet is a mid-round quarterback pick and waiting to see if someone like Lamar Jackson is available at the end of the first round of the 2018 NFL Draft.

The Quarterback Gambles

The biggest question for a lot of teams heading into the 2018 NFL Draft surrounds the incoming rookie quarterback class. There are four huge names at quarterback and a lot of NFL teams that wants one. At the moment, Sam Darnold is likely to be the top overall pick in the NFL Draft for the Cleveland Browns.

After that, it gets fuzzy. Baker Mayfield, Josh Allen and Josh Rosen are the next three to go, with Lamar Jackson as a wildcard. Teams needing a quarterback are the Cleveland Browns, Buffalo Bills, New York Jets, Miami Dolphins, Denver Broncos, New York Giants and Arizona Cardinals. Expect all four quarterbacks to go in the first five to 10 picks of the [VIDEO]2018 NFL Draft [VIDEO].
