I agree. As long as it was just spot duty, I agree JB should be the back up to get us through a short term Rivers injury. If however Rivers went down for the season early, I'd prefer to see what the young guys have to offer for the future.
I've seen mentions of Campbell in several articles. One was on second year breakout players on O. Let's face it though, most attention will be on Pittman as a rook, and TY as the aging #1 trying to rebound from injury. I'd say more folks are talking about him than Pascal, who was our #1 last year in terms of yards.
I fully expect Campbell to perform well this year if he's healthy, as I also expect TY and Pittman to do well. If I had to name a WR that I think will surprise, or outperform expectation, I'd pick either Dulin or Fountain.
That data in the tweet above is surface level at best, and lacks context. Take a look at the game breakdown above. It has more to do with playing 2 top five passing teams than anything else. Winston and Brees are two top 10 QBs (#s). And having zero offense for a few of those losses also added to the stress on our D.
It also doesn't account for other injured DBs during those weeks. IIRC, Willis, Desir, Wilson, Hooker, Geathers, and Rock all missed time or were banged up during that late stretch.
