I'm not that concerned with having an OC.
Mac got a good foundation with McD last year and hes working out hard this offseason. He'll be much improved next season.
The offensive system will not change but I think it'll be a little more streamlined and tailored more to Mac's strengths.
But I AM worried about the D. The D was great until the end of the season when they fell apart. We've heard from several defensive leaders, stand-up guys like Phillips and DMac,that after the bye the team just didnt seem mentally prepared.
I think theyre hinting at the lack of a DC, having one strong voice to narrow the focus where it belongs, hurt them. I have no idea what BB will do but it sure seems a DC is needed.
