I agree. I do think Rex is a good coach and was actually expecting more of an ego. He said some things at his initial press conference and a couple minor things before the NE game, but I too think that was overblown. But his ego has been in check thus far, not that there has been much to brag about to this point.
I have to imagine he did look at the defense and thought the talent would work in his scheme. But it looks like he really needs to adjust and maybe run a hybrid base D, with some of his exotic looks sprinkled in at times. He really needs to build his D and have the correct players to run his scheme, I don't think he has that here. And I am not saying the Bills don't have talent on D, I am saying these players do not all fit his scheme. And if 1 person isn't on the same page or isn't the right fit, the D as a whole suffers.
At this point, I am not sold on Rex. But I am not dead set against him and will not bash without knowing all the fact like most here. I am disappointed in the 3-4 start, but truly only thought they would be 4-3 at best to this point in the season. It's not over, but it's a bit of a cluster right now. I just hope this team can get healthy and stay healthy and then see what happens. It's not over yet...GO BILLS!!!!
