There is NO QUESTION that if these reports are true they are a significant red flag.
The guy has a lot of work to do and if he is unable to put in quality work at areas of need, he is unlikely to ever be worth a high draft pick...but to act as if these reports are absolute fact and that they prove that Geno will be a bust is being disingenuous and that's where this discussion turned into an argument.
It's possible that his unwillingness to focus on crucial points is a reason he faltered against good defenses last year.
It's also possible this is all BS info distributed by the agent he just fired...which is more likely givent the timing of the report in relation to the firing.
