"Correcting the problem started in recruiting, an area where Meyer believes the issue also began. The Buckeyes have missed out, been incorrect in their evaluations and been unsuccessful in developing players." If Luke Fickell cannot coach-up the LBs this year, he needs to be replaced. Get a great LB coach on staff that will make it happen. It seems tOSU is locked in to some sort of "affirative action program" with Fickell regardless of his results on the field. There is a reason no other teams are hot after Fickell's services... he lacks coaching ability. Based on the play of Buckeye LBs over the last two seasons (excepting Ryan Shazier), Fickell could be the most overpaid position coach of any major college program. 
I believe there are more problems with the LB position group than are being told. There are six scholarship players (including two true freshmen) and five walk-ons in the group. Two other Scholarship players transferred out of the program earlier this year. Fickell responds to questions about his LBs with platitudes and cliches but no real substance as to why this group is still struggling. Meyer needs to hold Fickell accountable for the lack of preparedness at this point.
I like your take on recruiting prospects except for Sam Hubbard. I think he sees himself as a game-breaking stud middle linebacker. The question is: How will the Buckeye coaching staff evaluate his best potential contribution? Will Luke Fickell argue to keep him at linebacker? Wouldn't it be great to have another monster in the middle of the Buckeye defense? But perhaps it's just wishful thinking on my part. 
I'm pleased both Meyer and Herman seem confident Braxton is improved since the end of last season but I can't perceive it yet. I thought his footwork was often wrong and his throwing motion still somewhat awkward. Maybe I don't know what I'm looking at.
