Updated 2015 Big Board

This is one week where it wasn't much fun to put the Big Board together, because the injury to Todd Gurley, a top-10 player here a week ago, obviously changes things. The good is that I don't believe Gurley's injury will drop him as far as some think if he chooses to enter the 2015 draft. I wrote about that here. But it does mean he drops off the Big Board for now.

There are three new additions this week.

As always, I'll keep scouting reports consistent week to week throughout the season and make changes regarding recent performances only, unless my evaluation shifts. That said, let's dive back into "the process" and another season.

An asterisk denotes a junior for the 2014 season; two asterisks denote a redshirt sophomore.

1. *Marcus Mariota, QB, Oregon Ducks

The Ducks had last weekend off, and Mariota has a pair of upcoming games where he figures to shine. As a passer, he continues to show improved accuracy and anticipation, and the ability to get through his progressions more quickly is obvious. Of course, elite athleticism is a huge part of his game, though how well he can take apart a defense with tools other than his legs matters. But his ability to throw on the run or simply take off and pick up chunk yardage is a major plus. This is a great kid with a sound work ethic and the chance to be special.

2. *Leonard Williams, DE, USC Trojans

He had another 1.5 TFL against Cal, but Williams won't be a huge numbers guy as much as he helps everyone around him. He provides impact wherever he lines up. Quick for his size, he can move all over and won't get pushed around when he's inside. At his size (6-foot-5, 290 pounds), he's a special athlete who could line up as a defensive end and drive a tackle back or line up on the outside shoulder of a guard and create problems with power and quickness. He's the kind of disruptive, versatile lineman who can succeed in any system.
