how much did Ohio's state income tax hurt the Cavaliers with LeBron?

From Michael Lee in the Washington Post...

If James signed a five-year deal with Miami, he could actually make more money than a similar deal with the Cavaliers because there is no state income tax in Florida.

I'm surprised that the taxes are that burdensome, but it certainly points to an important underlying factor for James (as well as Bosh and Wade). Beyond that, it points to an advantage that no-income-tax states have in professional sports. And it points to the economic difficulties which can be impacted, at the (sometimes considerable) margin-- by taxation and other economic policies.
