All of the numbers you see below are approximations. This is intended simply for fun, and
because this is intended simply for fun, we’re going to take two different approaches, because I can’t make up my mind over which is more accurate. Each approach will target a different single-season WAR. Obviously, the first step is figuring out James’ single-season value, and this is why we’ll have two approaches.
One idea:
last year, James was worth about 2.3% of all basketball WAR. Because a baseball season has 1,000 total WAR, that would give us a target of about 23.
The other idea:
James is projected for about 21 WAR. That’s over an 82-game season, so over a 162-game season, you’d be talking about almost 42 WAR. I don’t know which way to go, so I’ll go both.
