As some had indicated...Perry Hill wants to continue coaching...just not with the Pirates. Certainly with the statements we have now seen from Hill and management...mainly Huntington...it appears that any family concerns are not the main problem.
I see two possibilities...
1) There is a problem between management (read Huntington and Coonelly) and underlings. Buckley (minor league pitching coordinator) left...under somewhat uncertain circumstances. Now it appears that Hill and the management team were not on the same page. Whether it be promises that were made before he signed...or something he knows he was going to be expected to do next year...there is obviously enough hard feelings for Perry not to return.
2) It's about the money. This one I find hard to swallow. Coaches aren't millionaires...at least most of them. I've seen Dave Duncan anywhere between $800 K and $1M. Rudy Jaramillo signed with the Cubs today for 3 years/$2.4M. So...if it was about money...can't imagine it would be more than a couple of hundred grand. Russell is at $800K as manager. If that small amount of money is a problem...the Pirates are in deep trouble.
My guess...possibility #1 is real close to the truth...and we may never find out exactly where the problem is...but there is one.
