I disagree. Boldin is in the top 20 in targets (#19), total yards (#17) and top 10 in YPRR (yds per route run). Calvin isn't even top 30 in YPPR (#31 - can't use him missing games as an excuse here), #30 in total yards (yes he missed a game), and #22 in targets (yes he missed a game). There are no disagreements that a healthy Calvin is money, but there should be agreement that Boldin's production this year has also been money. The only downside is that his production is feast or famine depending on whether SF wants to Gore the other team on the ground.
Outlining Boldin's uneven production:
Week
1) Green Bay, strong run D, weak secondary, start him. = 26.8 pts.
2) Seattle, strong run D AND secondary, bench him. = 0.70 pts
3) Indy, average run D, weak secondary, start him. = 6.70 pts
4) StL, horrible run D, above average secondary, defense is in bottom third, autostart. = 15.00 pts
5) Houston, average run D, weak secondary, start him. = 2.10 pts
6) AZ, above average run d, weak secondary, start him. = 2.80 pts
It will be interesting to see if he blows up against another strong run D, but we won't see that until Week 14 vs Seattle, and unfortunately they have the Legion of Boom so you bench him. AZ was a big test, but SF's OL won that battle handily and Boldin wasn't needed as much as we thought. So his production will remain unpredictable.
