Irvin was on 105.3 the fan this morning. He said he played in the Pro Bowl under the 49ers West coast offense. He said it was extremely difficult to understand, but Aikman was so cerebral, he was able to understand it and simplify it for Irvin. Think about the QBs McCarthy had under this offense.... Montana, Steve Young, Favre, and Rogers. They all had high QB IQs. I think Dak will be just fine.
