I think we'd also need to factor in the effect that sproles had on defenses though
Agreed he was not great last year, nowhere near his 2011 form but even if he wasn't the primary receiver he made an outstanding decoy because he was a threat to take it the distance at any moment

I personally don't think teams fear Cadet like they did sproles
Plus with teams getting pressure against us sending 4 guys, they can drop 7 back into coverage - the same reason Brees has struggled against teams like the rams for years.
