Why Is Smokey Joe Wood Not in the Hall of Fame?

This isn't an article as much as it is a question in need of comments.

Many historians believe that Walter Johnson is a top tier Hall of Fame starting pitcher and he might make it in many historians all time five-man rotation, and I agree, it's at least arguable.

What we have to remember is that when Johnson and Smokey Joe Wood both played, the question was: Who's Better Walter Johnson or Joe Wood? Back then, it wasn't a question that was easily answered.

In fact, more people than you might think thought Wood was as good or better than Johnson at the time. How we ever lost sight of that is beyond me.

What spurred me to write this was the Jamie Moyer article asking if he should be in the Hall of Fame. Moyer is good, not great, and it just got me thinking about Smokey Joe.

To keep you from having to look it up, some Smokey Joe Wood stats and facts: 2.03 ERA (third all time), .672 winning percentage (top-10 all time), pitched in just over 200 games before he threw his arm out, gave up only 10 HR during his career (amazing, even for the 1910s)

So here's why I'm requesting comments:

Give me a reason, other than his short career, that Smokey Joe Wood is not in the Hall of Fame?
