"I know these guys, these owners, they want to win," said Evans, who along with Yaz was recognized as part of the All-Fenway Park Team prior to Wednesday night's game against the Rays.
Count Evans among those who endorsed the trade that sent Adrian Gonzalez, Josh Beckett, Carl Crawford and Nick Punto to the Dodgers for prospects.
"Well, obviously we're going to rebuild," Evans said. "We're looking at that. We looked at a trade a month-and-a-half ago that I thought was a very interesting trade and a good trade. So I think it freed us up to go and interject some quality players into the core that we have, that we've raised through this system.
"I'm not sure that's their plan, but I would think it is. I know that they want to win. They love being in that winners' circle and I think they're dedicated. I don't know when it's going to be. I don't know if it's going to be two years, three years, but we will be back."
Yastrzemski is a fan of Red Sox general manager Ben Cherington, whom he got to know when Cherington was in a previous role with the club as farm director. Yaz works every Spring Training with Minor League hitters in Boston's system.
"The Red Sox will be back," Yastrzemski said. "Ben Cherington did a great job in the Minor League system, don't you agree? He's a good baseball man. And the one thing I like about him, he asks for your opinion. It's not like, well 'I know everything.' He'll ask people for their opinions, which is a good sign. No one in this game knows it all."
