Well, you'd be wrong. http://www.overthemonster.com/2016/5/9/11639650/red-sox-rich-hill-free-agent-rumors
President of Baseball Operations Dave Dombrowski makes it clear he believes that the spot the A's could offer was the real decision maker for the southpaw.
"We like what he did for us last year," Dombrowski said. "He pitched very well. It wasn't like we could look at him and say he was a guaranteed starter. We knew we were going to try to add a guy at the top of the rotation. He would've been in competition, and he also would've been a guy if he wasn't starting for us that we could've put into the bullpen. But he just had such a good opportunity with Oakland."
