Bucks in 5. Bucks hold serve in Games 1 & 2, Celts win the vital Game 3, but the Bucks take game 4, then seal the deal in Game 5.
The Pacers series was a lot shorter than I anticipated, but the games were about as close as I thought they'd be. The Pacers had some bad luck and some unfortunate miscues, coupled with the Celts hitting some clutch shots. A mix of having more shot-making talent and some good luck.
So I'm going to stick with my prediction of Bucks in 5.
