Cassidy admired the Red Sox' ability to gather contributions from up and down the lineup, pointing specifically to the performance of first baseman Steve Pearce, who was named World Series MVP after launching three home runs - two in Game 5 - and driving in eight runs.
"I gotta tell you, I don't know a lot about him, but it's a great story. I love it," said Cassidy. "I'm sure he's a very good major league player, but to get the MVP - you're usually thinking of a big-name player. So it just tells you a little about their team. Also Jackie Bradley Jr., a hero and then they're able to sub other guys in there.
"To me watching, it was such a team effort. Their best players have to be their best players, but it was good to see them getting contributions from everyone. As a coach you love to see everyone do their part."
Cassidy also lauded the work of first-year manager Alex Cora.
"I'm happy for him," said Cassidy. "I congratulate the whole Red Sox organization, the players, management, staff. To Alex, personally, I think he's done a great job there. As a fellow guy that runs the ship, I'm happy for those guys and I thought he made a lot of great moves.
"And his players, when they produce, make him look good as well. But they fought through whatever adversity they had, so very happy for them."
