Woops! Our Biggest Fantasy Football Mistakes of 2016

Here at RotoViz, we don’t only write about fantasy football, we play it. When we offer advice, it’s usually because we’re making similar moves. In the spirit of accountability (and laughing at ourselves), here are the worst moves we made in 2016….

Historical Comps for Hunter Henry’s Rookie Season

Charles Kleinheksel has begun a series of articles looking at rookie wide receivers, and placing their first NFL seasons in some kind of historical context.

3 Big Surprises in the 2017 RB Prospect Lab Rankings (Pre-Combine)

The RB Prospect Lab is one of my favorite apps. It’s a draft-agnostic tool that allows you to input age, size, speed, agility, production, and receiving ability to get a scaled projection of future fantasy prospects. You can experiment with the variables to see how they interact, or you can work with real prospects to get a feel for their NFL viability…. Membership Required You...
