I love the RB argument.
I am 100% on the side of the RBs. I believe without either one of the greatest QBs of all time or an elite run game you aren't making noise in the playoffs when it matters most.
Everyone needs to stop looking at Patriots when Making arguments. They have THE GOAT in Tom Brady. They have THE GOAT in Bill B. They are defensive guru's year in and year out. Tom Brady takes a pay cut to allow the Pats to pay people around him. They are the greatest franchise the NFL has ever seen. Teams need to stop trying to mimic the Patriots and fans need to stop using the Patriots in arguments. They will always be the outliers to every argument.
With that said....
I would NEVER use a 1st round pick on a RB, and my reason is $$. In the first round I would always focus on drafting valuable high cost players. Certain positions - QB, CB, EDGE, OT just cost substantially more than other positions. If you try to get a premiere guy at these 4 positions in FA you are probably spending close to $14+ M annually.
If you can draft that position in the first round and get that 5th year rookie option you can save TONS of $$ and afford to pay other positions with premium $ for a few years until their 2nd contracts are due. When I say other positions, I can include RB in that argument. It seems year after year (minus Chip Kelly and D Murray) you can get the most elite RB FAs for $6 M and even less range.

If you want to look at examples of teams that just have pretty good QBs and devalue the RB position look at teams like the Redskins under the Cousins / Gruden regime. They have peaked, and that peak involved being smashed in the first round in a down year in the NFC East. Even when you look at past super bowl champions and super bowl contenders that do NOT include Patriots, most of those teams leaned heavily on the run, including the great Peyton Manning and his 23 Super Bowl pass attempts.
I understand and appreciate what everyone here is saying and I like the debate cause I feel like no side ever convinces the other side. I respect all of yalls opinions on this matter, but put me in the "Give me Brady or Elite FA RB Camp that won't spend high pick on a RB".
