Seems we now have two offensive QC coaches.
Reich and Sirianni have connections to Rivers, so it makes sense that these rumors are floating around. It would make sense if Reich/Sirianni feel like River's is a significant improvement over Brissett for them to bring him in, since he'd have a good feel of the system right out of the gates.
However, while I agree another season of JB may offer no top-tier QB play, I don't think it stops us from being able to win. Ballard said since day 1 that he doesn't build teams just around 1 player. We didn't get the greatest QB play from Brissett last year, but we had injuries all over the board and we had some really close games lost. For example, we could've easily been 9-7 or 10-6 if Vinny didn't have his kicking woes. We split with the Titans and Texans. The Titans went on to the AFC Championship game as the 6 seed and put up a good fight against eventual SB Champs KC, who we beat early in the year. If we improve our DL, keep our OL intact, and add some depth across the board and stay healthy, this team is very capable of winning the AFC South with Brissett at QB.
