Not sure how someone can be thrown into a "best ever" category with a rather mild single season performance.
1086 total yards from scrimmage and 8 total TDs doesn't scream "best ever" in any category. Especially in the same season Hunter had 1083 receiving yards and 9 TDs.
I could see CP's lone season being up there as one of the better seasons by a WR here though, but not sure I can put him ahead of Kent, Nash, Pickens, Meachem, Price, Hunter, McGee, Moore, Washington, Hancock, Seviers, or even Wilson.
