So if you take Roy/BJ/Sloane over Collin/LJH/Duvernay (I agree with you there)...
Who do you take between the Collin/LJH duo vs the Shipley/Quan duo? As you just noted, statistically they are very similar, but this years group is doing it with inferior QB play. The older duo could both give you a punt or KO return for a TD, but the newer group is more physically gifted and tougher for DBs to match up with.
I think I would lean in favor of Collin/LJH after realizing they are statistically equal this year.
