I would nuance it a little bit and say it was Becks fault (that he isn't very good at his job) but Urban Meyers responsibility(in making the hire).
And deployment, and switching, oh mercy, the switching.
From the POV of just a guy on the street with no inside info it's hard to get past the change that came over the offense once Warriner went up to the booth along with the comments about play calling from Zeke and others.
I think they got much better at running the old scheme, which isn't what Urban ultimately wants to do, and isn't what Dwayne or Danny can do (Joey might be able to it but he's more adept than dominant as a runner).
My concern is that that the alleged fix did not address the flaws that have held them back in early 2014 and in the two years before that (which were coached by an offensive savant, which gets back to my point about the real source of the problem not being the OC let alone the second one).
Will they lean enough on the tailback when things get tight? Urban had this fatal flaw in key losses in 2013 & 2015 and I don't like thinking about that tendency with a very young and inconsistent team facing a tough schedule with uncertainty at tailback. Best case scenario is probably similar to mid 2014 with Weber emerging as the guy. It seems much more likely that they have some sort of committee (or a head guy that they don't lean fully upon), and that makes me worry about a head coach that resorts to QB runs when things aren't going well.
I'm concerned about whether the passing game will step up. Will JT develop considerably in his field vision, timing and accuracy? He wasn't the main problem last year but he certainly didn't help (nor did Cardale). Both were capable of passing well but often were inconsistent and JT was really struggling late in 2014.
Will the wideouts get good separation? If Brown is fully healthy, which is unknown, he should provide a nice boost as a blocker but chances are he will be behind Thomas as a possession guy (that seems like a near guarantee). Corey Smith can separate but is not the most consistent receiver in traffic. Chances are he is a faster, less physical replacement for Jalin, though Corey's blocking will be a welcome addition. Then there's the slot. Will it be Curtis Samuel, who is athletic but more of an athlete than a pure WR? Will it be a dynamic, green young guy like Austin Mack at times? Braxton was a devastating athlete that is pretty tough to replace. The one boost they might get here is the ability to have a better blocker in Curtis as Braxton's blocking left a lot to be desired.
Hopefully the protection will be better with two more natural tackles, though that remains to be seen. The other guard spot is concerning and even Price has been an inconsistent protector. That's troubling. Fortunately this team looks a lot better on paper when it comes to perimeter blocking. That was as big of a loss as Devin's deep speed was the great blocking from Evan, Noah and Corey.
Will Urban decide what scheme he wants to run and stick with it? Because that doomed them big time last year.
Does he have the coaches to scheme and develop a more polished passing game? Or does he still have two read option guys working for a read option head coach? (hint: I think it's the latter) There was a lot of talk about Tebow's final year and getting ready for the NFL. I didn't follow it closely but I don't recall it achieving the evolution they hoped to achieve.
I think Beck has his flaws and limitations. I think all of the above issues are glaring flaws that aren't Beck's fault and frankly that responsibility and blame lies with Urban.
