I agree with the OP for the most part. To me the biggest difference between Geno Smith (the standard bearer in rookie QBs this season in spite of some of his struggles) and EJ's development, is the fact that Morhinweg is a veteran OC who knows how to develop QBs (Jets, Green Bay, SF, Detroit). We have a rookie OC who has trouble calling plays let alone developing QBs.
In contrast, our D has a veteran talent *and* a veteran coach who knows how to use that talent.
I'm all for Hackett being the OC next season, but I think we need to bring in a QB coach who knows how to develop QBs. I also think we need a new ST coach.
