Bills trade with Browns, nab Sammy Watkins; Raiders steal Khalil Mack

The Buffalo Bills made the first big move of the night by trading up to the fourth-overall pick (previously held by Cleveland Browns) to select Clemson wide receiver Sammy Watkins.

To move up spots, they gave up their No. 1 pick in the 2015 NFL Draft, as well as a 4th-rounder in '15. The Browns now hold the ninth-overall pick.

In his scouting report on Watkins, SB Nation's Dan Kadar noted that the sure-handed playmaker has more upside than any other receiver prospect in this class.

Watkins is a sensation of a wide receiver. As a player, there are few flaws in his game. Those that are there - running a more diverse route tree, catching the ball when pressure is closing on him - are coachable points. Watkins is the type of receiver who can be brought in, start straight away and become a star. Expecting him to have the same type of impact A.J. Green did for the Bengals should be the expectation.

With the fifth-overall pick, the Oakland Raiders selected Buffalo outside linebacker Khalil Mack, who was once in contention to be the first-overall pick, but fell to the linebacker-needy Raiders.
