Whether Denny has specific ideas or not, does standing pat work? I suppose it can, but the Sox did stand patafter 2013 and the results could not have been worse.
Look at the Yankees from 1996 to 2000. How many players played the same position for all 4 WS titles? Four? Maybe five, if you want to consider Rivera a relief pitcher and not a closer.
They had lots of turnover, especially in the rotation, where only Pettitte was around for the entire run. The bullpen was actually more stable, despite the rude thinking that relievers are crapshoots...
