Reggie Mckenzie should be first. That roster has somehow gotten less talented since he showed up. Simply atrocious handling of the QB position.
People here were mad at Fitz being given a contract? Mckenzie traded away Palmer (a ten win starter last year) and picked up Matt Flynn for a 6th round pick and drafted Tyler Wilson in the 4th round only to cut both of them before week 6 last season and start Matt McGloin most of the year who is a poor mans Fitzpatrick on his best day.
Then to stabilize the position he traded for Matt Schaub, who anyone who watched a game last year could tell you his arm is dead, and gave him a nice payday too to back up Derek Carr. Carr has looked like a poor starter for a team with no talent
Dennis Alllen walked into an impossible situation with an unstable roster and salary cap hell and his GM has been equally awful
