Darren Waller was a household name for Raider Nation during his five-year stint with the Oakland and Las Vegas Raiders. His rise from the Baltimore Ravens practice squad to Pro Bowl-level player was a sight to behold, and he'll always be a fan favorite for the Silver and Black.
Of course, his tenure with the team ended unceremoniously under the regime of Josh McDaniels and Dave Ziegler, but that was a dark time in Raiders history, and it is hard to blame Waller for not wanting to be a part of that.
He was eventually traded to the New York Giants for a third-round pick, which turned into Tre Tucker.
