How Darius Garland's 'pivotal' season is fueling the Cavaliers

Darius Garland has been a driving force in Cleveland Cavaliers' success this season .

The Cavaliers have the NBA 's best record at 48-10 entering Friday night 's road game against the Boston Celtics .

The possibility of a Garland trade was a frequent discussion point in the weeks following the Cavaliers ' second -round playoff exit.

"He's looking like his old self again again," says center Jarrett Allen .

Cleveland Cavaliers guard Jordan Mitchell signed a contract extension with the Cavaliers .

The Cavaliers lost to the Celtics in the second -round of last season's playoff series.

The 25-year-old is hoping to return to his All-Star form in the playoffs.

Mitchell says he has been the biggest catalyst for the Cavaliers ' improvement.

Garland credits Mitchell 's sacrifice for setting the cultural tone in Cleveland this season .

Mitchell : "He can be ultra-aggressive and go out there and get 30 whenever he wants to" Paul : "When you got two ball-dominant players, they have to get a rhythm. It takes the effort to stay consistently successful".
