For a second year in a row, the Indiana Pacers are back in the Eastern Conference Finals. No one thought we would be here again — especially not after Indiana's slow start to the season.

Tyrese Haliburton, Pascal Siakam and the rest of the a deep Indiana team square off against an old nemesis in a wide-open NBA postseason.

The Pacers' success, particularly on offense, is the product of a group of players that has bought in and a coach that has evolved.

As four teams battle for the title, 26 teams are looking to improve -- and watching the conference finals can help.
