My view on the situation on offense is that the issues are probably easier to fix. A few better play calls (which might come down to a bit more hand holding really) and a lot of the offensive issues go away. On the other hand the defensive issues are more disconcerting because the question is basically whether or not some rot has set in. There are some positives there but the scoring offense is ranked #2. The scoring defense is ranked #35. Still a lot more worried overall about the defense...Nope. And there's no guarantee he won't be here next season.
I also don't think he's as bad as some here seem to think. Could he call better games? Sure, he's no Sark. But I think he's done a solid job overall.
