Joe Mixon represents a huge loss for the Cincinnati Bengals

The Cincinnati Bengals arguably made a huge mistake by ditching Joe Mixon.

He was coming off the fourth 1,000-yard season of his career, but instead of recommitting to him, they just traded him to the Houston Texans for a mere seventh-round pick - a shockingly poor return for a player of his caliber.

The man who replaces him, Zack Moss, has proven himself a capable backup through his career. But excelling as a starter may be far-fetched.
