No it's not crazy.
Having a good but not great, not great leader for a QB on $40m+ a year without a great roster around him is a sure fire way to be mediocre for many years. Especially in this division.
It's not crazy to think of a scenario where we start again with a boat load of picks to rebuild the squad.
And there are some QB's that have not quite made the grade in the NFL that I would be interested to see what they could do in Kliff's pared down, more basic college influenced offense. Guys like Winston, Marriota, Minshew and Trubisky. These guys were drafted where they were for a reason but just couldn't quite adjust to life in the NFL. Kliff's scheme might be the difference.
Until a draft comes around with a QBOTF.
