I can pick nits about his drafting but no GM hits on all picks so am going to ignore that for a moment,
IMHO, his biggest failing is the choice of coaches. Marrone followed by Ryan is one disaster after another. Ryan is looking terrible for (1) his complicated and ineffective defense (2) lack of discipline manifesting itself in the chronic problem of penalties, and (3) didnt know where to assign blame but it appears to me that there are more injuries this season than in the past two. Strength and conditioning ?? (4) Crossman - known in Detroit for his poor STs, he did fairly well with Marrone. What happened this year ?
I had pointed out early in the season that there are some disturbing patterns emerging which would be glaring once the 'honeymoon period' was done. Needless to say, we are there now. Whaley has to take the credit (Roman) as well as blame for this coaching staff
