I would tend to not question Jerry Kill's motives on this too much or read too much into anything you read on this matter.. The GI in Iowa post is very valid.
If Kill indeed moved back to his "lake" house in Illinois, that makes sense. He has lost most of what he spent his whole life working to achieve and did not make it due to health issues. Being on the sidelines in Minneapolis as he watches things play out, good or bad, has to absolute torture.
Some guys like Glen Mason, really like the metropolitan aspects of Minneapolis and living near Lake Minnetonka. Jerry is more of a non-Chicago Illinois kind of guy, not too over analyze, since I think he and RK did relish their non football time here. I know if I lost my job and had a 200K salary on the way, but plenty of tough memories I'd move to Illinois too. I'd just move to a warehouse style condo in the River North Chicago or the Gold Coast and take my lumps there. I'd also try to get a job at the Big Ten Network and maybe have a couple of martinis with Taylor Rooks!
Jerry is a different kind of guy than Mason, but I think that Jerry Kill and RK did really embrace living here though, and it is a shame if they really did sell their house in MPLS. I saw JK and RK walking all the time around St. Anthony Main and the Stone Arch Bridge the last two three years as he tried to get more balance in his life. I think I saw his brother as well who looks a lot like JK if I am right, but I really think they liked it a lot here.
The issue for JK or at least (would be for) me is that it is very painful to watch this all at close range, and it does not really help Tracy Claeys much either. Jerry is fighting through a lot, and I am sure being secluded in rural Illinois in a paid for "lake house" is a better than marinating in what just happened to his career.
