In terms of player talent - i answer a resounding no.
In terms of scheme/coaching - I think that is the difference - and you see it the in coaching staffs of the final 4 teams again this year.
Dallas has what, 6-7 probowlers, plus add Freebeard,Amari Cooper, Jaylon, Awuze is pretty close, and a couple other solid players. You saw Gregory's talent, but inexperience limited him in playoffs. Irving is another in a long line of guys that let us down with off-field issues and drug struggles (yes, mental illness is sad, if that is what it is - still sucks when it hurts your sports team). We have some real talent, and some of it quite young in our top 25 "starters".........
Not many other teams have that much. With the relative youth, we have a window of time with Tyron, and Zeke (mileage will catch up), and the salary cap, etc..... It will be up to coaches to put team in position to succeed and win, in many ways.....Have to play to team strengths. The oline coach was a disaster (Cinci guy) trying to change our studs. Linehan was uncreative and stubborn and didn't play to Dak's strengths. Lots we don't see though - why is Garrett not seeing that - is Jerry undermining and forcing guys on his coach, etc etc....
I think we heard teams say 3 or 4 times this season, other team knew what our team was going to do, mostly on offense, but then on D against Rams too - in this day and age - trying to win under those circumstances is probably next to impossible. Game comes down to 2-3 plays and milliseconds and inches each week - not to mention probably a weird ref call or two.
Close, but it takes pretty much everything gelling to win championships.
