How do you explain situations like the Cleveland Indians where they went from a 90+ loss team one season to a 90+ win without making any major changes other than the manager? They have to be at least part of the reason for that, right? For the record I'm not saying I believe any specific manager will make us 30 wins better but there do seem to be examples where a managerial change makes a big difference. Is it a matter of a bad manager making the team worse as opposed to a good manager making the team better? Ummm.......Because they had a lot of guys have better years on offense and pitching than the year before Indians 2012 offense: http://www.fangraphs.com/leaders.aspx?pos=all&stats=bat&lg=all&qual=0&type=8&season=2012&month=0&season1=2012&ind=0&team=5&rost=0&age=0&filter=&players=0 Indians 2012 pitching: http://www.fangraphs.com/leaders.aspx?pos=all&stats=pit&lg=all&qual=0&type=8&season=2012&month=0&season1=2012&ind=0&team=5&rost=0&age=0&filter=&players=0 Indians 2013 offense: http://www.fangraphs.com/leaders.aspx?pos=all&stats=bat&lg=all&qual=0&type=8&season=2013&month=0&season1=2013&ind=0&team=5&rost=0&age=0&filter=&players=0 Indians 2013 pitching: http://www.fangraphs.com/leaders.aspx?pos=all&stats=pit&lg=all&qual=0&type=8&season=2013&month=0&season1=2013&ind=0&team=5&rost=0&age=0&filter=&players=0 Ok, do the manager & his staff not have anything to do with that?
