How much will the Mavs be hurt by not having Butler in finals?

Hard to say, but the Mavs will need all hands on deck. The Heat are damn good, and they could not pick a better time to be playing so well. No one from the Mavs will keep Lebron in check. No one. I hope the mavs win, but the difference will be legs. I do not think the Mavs can run with the Heat. If they have a high shooting percentage, they have a chance. If not, Katie bar the door because they will be in trouble.
