Sitting too close to the TV is terrible for your eyesight. Everyone knows this, as parents have ingrained it in their eager children for nearly half a century. There’s just one small problem with this generally accepted fact. It’s not a fact.

Nope, the American Academy of Opthamology says that sitting too close to the TV won’t cause any physical damage to your eyes. Every TV made after 1968 is just fine for your eyesight, even if you sit really close. There’s a difference between what you know, and what you think you know. It's the same in fantasy football.

The Myth of Wide Receiver Depth

The book on wide receivers versus running backs is the same this year as it has been in the recent past: backs are top-heavy, so you should grab them first. You can wait and still pick up quality wideouts. Here at NumberFire, we’re in the business of using numbers instead of “the book.” So what do the numbers say about wide receiver depth?

Last year, running back was actually deeper than wide receiver. Four wideouts topped 200 fantasy points. (Standard scoring, non-PPR leagues.) Compare that to 10 running backs. But the top tier alone doesn't signify positional depth. Surely there were many more viable fantasy receivers a rung or two below the top guys, right? Wrong. 12 WRs put up at least 170 points; 14 RBs did the same. 18 receivers put up 150 points, versus 19 backs. Only at the very bottom of the respective positions did wide receivers outnumber running backs and even then just barely: 25 receivers put up 130 points, as did 23 running backs.

2012

But one year isn’t a very large sample size. In 2011, the same trend - running back being deeper than receiver - held true:

2011

Let's make it an even three-year sample size. In 2010, backs blew receivers out of the water.

2010

So last year, running back was just slightly deeper than wide receiver. In 2011, the gap was even more pronounced. Same in 2010. What about this year? Despite basically everyone beating the drum for wide receiver depth, according to our projections, it’s actually running backs who should have the deeper pool. Acknowledging that projections are an inexact science, we have eight backs projected to top 200 points, compared with just two receivers. Including the next tier, we have 17 running backs projected to top 170 points and 14 wide receivers set to reach that same mark. If anything, running backs appear to be the deeper class than receiver this season.

Calvin Johnson and Value

The true value of a first-round fantasy draft pick is in security. Unless you get a superlative year from someone like Matthew Berry and ESPN Stats & Info.)

So that’s what you’re getting with Calvin Johnson. And right now, you can get him with the 10^th pick in your draft, on average, per fantasyfootballcalculator.com. But is he even more valuable than that?

Since he’s clearly the top receiver, let’s compare him to the top running back. Last year, Johnson put up 220.4 fantasy points. Adrian Peterson put up 307.4 points. There was a 22.2 percent gap in production between Johnson and the 10^th-best wide receiver (wide receivers tend to be much more volatile than running backs. But then there's Calvin Johnson, who provides consistent week-to-week production (he had just three "dud" games of under 5 fantasy points over 2012 and 2011 combined) that makes him even more valuable when compared to other wideouts. Even the most bullish Calvin Johnson fans won’t suggest you should take him number one overall, or even top three. (Unless you’re in a PPR, three-WR league, in which case you might consider it.) But 10? He’s been comparably valuable, relative to his position, to the top running backs in the league the past two years, but you’re going to pass on him to take C.J. Spiller? If you’re sitting in that 4-9 range, you should take a long, hard look at Johnson. Think about what you know about depth and value, and then think about what you think you know.
