For his first three years in the NFL, Chris Johnson was one of the most underpaid backs in the NFL. He made about $7.7 million.
For the last three years, he's been more than fairly compensated -- collecting $34 million.
So to those who think life is unfair for Johnson right now, I'd say it's as easy to look at him as fortunate as well as unfortunate.
If Johnson was drafted years earlier, he would have been very well paid. But if he was in the 2014 draft, he would never line up for anything close to $41.7 million in his career.
His career has straddled a seismic shift in the economics for running backs.
ESPN.com's Ashley Fox runs through the harsh realities of that.
It's tough timing for CJ now. He'll likely get a reduced role and a contract with an annual value of $4 million or less. But at least he had six years of the old economics.
Going forward, here's a look at the Titans and running back money:
Titans' running back salary-cap costs in 2014: Greene $3.23M, McCluster $4M, Battle $570k, draft pick $435k + prorated piece of bonus. Total $8.235M + prorated bonus for the rookie.
