Paul Pierce still believes that the Celtics will take down the Knicks in their second-round series, but only if they change their 3-point approach and get tougher.

Following the Celtics' Game 1 loss to the New York Knicks in the Eastern Conference semifinals, Pierce vowed on FS1's "Speak," that he'd walk to work the next day in his robe. Unfortunately for him, the Celtics blew a 20-point lead, losing 91-90, and he made a 20.2-mile walk on Thursday.

The Hall of Famer is making the trek after he appeared on FS1 ahead of Game 2 and vowed to walk to the studio on Thursday if the Celtics lost.
