When Mike Macdonald hired Ryan Grubb to be his offensive coordinator back in February, we looked back through modern NFL history to find success stories from guys who had made the jump from college coordinator to NFL play caller. There were few to find.

In fact, a notable failure involved another former Husky, Steve Sarkisian, who joined Dan Quinn in Atlanta and promptly took that once vaunted offense backward.

We wrote then:

Grubb’s success or failure will come down to whether he can maximize his players. The biggest challenge for most play callers – certainly for Seattle’s last few – has been adjusting within games to what defenses are stopping. Grubb and company faced an NFL-style defense – one put together by Macdonald, in fact – in the title game against Michigan, and they had major trouble against it. Grubb will need to show he can adjust when his script fails. … It won’t be a shock if Grubb ultimately doesn’t have the answers.”

Well, Grubb has not proven to have the answers in his rookie season. And, if his unit continues to fail, it would not be a surprise if Macdonald followed Pete Carroll’s path and fired his OC after his first year as Seattle’s coach.
