If you get Daton for a 6th rounder like Carson Palmer, than you stole 2 QB from Cincy & Oakland that can be good enough to bring you to the playoffs.
That is more you can ask for.
On the other hand, Dalton is very inconsistant, like Palmer, he doesn't have the "I got you" wipe around you like Rodgers, Brady, Brees, Eli Manning (When on fire), Roethlisberger, Luck when healthy or sometimes Wilson(and sometimes he needs the D so badly to stay in the game that he can make that game wining drive).
And no Cam doesn't have it, Cam is I win it from the get go or I surrender it. Like Matty Iced ... he isn't good enough to win you the game. But they are good enough to put your D in position to win it, same goes for Flacco, Cousins, Carr, Wentz, Goff, Foels(under the right system), Stafford, Smith, Garappolo(from what we saw he could be better), Watson(for what we saw), Dalton, Rivers, Bridgewater(before injury), Bradford(when healthy) and Palmer (was on this level too expect for 1 season and post season in post season he somehow only showed up once).
Brisett, Taylor, Keenum, Gabbert, Stanton and so on, need a D to win the game, Prescott needs Zeke and the D. But ultimatly some of them aren't able to win the game without the D.
And that means only 4 teams have a QB that can shoulder the team at the moment and win it for them. Luck, Manning,Wilson aren't at that level, Manning isn't anymore, Luck maybe will never be again and Wilson is to inconsistent between really bad and good enough.
So when you don't have Roethlisberger, Rodgers, Brees, Brady you have to hope for a great D player that comes up strong. When Payton won his second SB it was Von Miller.
And Dalton didn't cost them the last 2 playoff games, one was soley on Burfict.
For me, Cousins/Dalton with our D and good ST play, can be a QB that is good enough to go every year to the playoffs, and with a good postseason run they could end up winning one or two SB, maybe in the right situation even more or none because of bad luck.
You don't know. Would I pay Cousins 20 Mio $ a year, yes, but 30 Mio $ will be maybe too much, expect someone knows exactly how to use him(and Washington is a bad franchise, they wouldn't recognize a franchise QB even if one would win them a SB expect it is the Backup and played only the SB and won because pure luck).
Would I take a risk on Luck if aviable, yes for sure, Brees showed you can have luck with that [luck with Luck ...]
I wouldn't touch Eli, Rivers or Smith. Eli isn't good anymore, not bad but not good enough, Rivers is to old for what we need and not good enoug and Smith showed, even with supporting Cast and D he can't win it all or go further in the playoffs.
Taylor for me is a interim QB a bit better than Gabbert or Stanton but not good enough. Bridgewater would be a game Manager like Smith that in my Opinion was good enough to win it all with a good enough D and RB support. Bradford ... is Bradford you get what you pay for he will miss some games.
So really it is, signing Cousins, trading Dalton or sign someone else and draft a QBoF. So yes no rebuild, but a new QB it will be, they will draft one this year, depending who is the starting QB it will be a #1 #2 or later round pick. And I wouldn't be surprised if they pick a small school QB or a sleeper like Riley Ferguson, Kyle Lauletta, Nick Stevens or Jeremiah Briscoe. And no I'm noit saying that any of this 4 guys is a NFL starting QB by now, but this guys have the potential to be at least a good Backup and they would be cheap, behind a expensive veteran QB. Although I think now Lauletta will rise to at least a day two selection as a pro style QB he has something many other QB in this draft don't have.
