All-time best Red Sox lineup: 3. Ted Williams, LF
The case for Ted Williams, I believe, is best told through who is omitted from this team because of him: Carl Yastrzemski. Yaz racked up 96.5 career WAR for the Red Sox during his 23 seasons with the team, he is second all-time in terms of WAR in franchise history, and is rightfully considered one of the greatest Red Sox of all-time ... but he'll always have to settle for being the second-best left fielder in franchise history, because no matter what, Teddy Ballgame will always be No. 1.
Williams racked up 121.8 career WAR during his time in Boston, far and away the highest amount of career WAR in Red Sox history. Of course, that number could've been higher had Williams not gone off to both World War II and the Korean War during his career, but still nothing much more needs to be said than the fact that a member of the MLB All-Century team just has to be in the lineup.
Williams slots into third in this lineup, keeping the lefty-righty balance in my lineup. Williams is getting hits, he's driving in runs, he's hitting home runs, he's going to do it all in this lineup. I don't need to make any more of an argument for him, he's Ted Williams. He has a tunnel named after him, for goodness sake!
