I found this mock. Now, bleacherreport tends to do a LOT of mocks (one per day), with a wide assortment of players being drafted in each version; so, take this with a grain of salt. Regardless, this is interesting.
I find these picks to be very good/interesting.
R1: Vaccaro, SS, Texas
I like Elam, but Vaccaro is 1-a. Thus, I am a fan of this pick.
R2: Ertz, TE, Stanford
I've asked: if the Steelers are planning on drafting a big WR, why not go for a TE instead? I've also averred that if Ertz drops to them in R2, he'd be difficult to pass on. This is a very intriguing pick.
R4: Hodges, LB, Penn St.
A player that many have mentioned.
R6: Carder, QB, Western Michigan
I like this pick... because, it's who I had the Steelers taking. Nowhere else have I seen Carder's name mentioned, let alone mentioned in connection with the Steelers. I'll take this as a "sign."
