Brad Stevens and the Boston Celtics are preparing to take on LeBron James and the Cleveland Cavaliers in Game 1 of the Eastern Conference Finals. After mixing up his lineups repeatedly throughout the postseason, coach Stevens had everyone guessing for most of the week as to who they would start in Game 1.

On Sunday afternoon, about an hour before gametime, Stevens announced that forward Marcus Morris would be starting against James on the Cavs.

Earlier this week, Morris proclaimed himself the best LeBron James defender outside of Kawhi Leonard, which certainly caught the eyes and turned the heads of many.

The Cavs won two of three matchups this season, including their opening night game where newly-signed Gordon Hayward went down with the freak leg injury and everyone thought their season was over. They fought, however, and fought harder than anyone expected to under head coach Stevens. Now, they have a chance to upset the Cavs and end LeBron James' run of Eastern Conference dominance.
