Hindsight aside, Pierce had reason to be optimistic. The Celtics are the reigning NBA champs, have home court advantage over New York and were betting favorites to beat the Knicks. Plus, blowing a 20-point lead as the favorites in the NBA Playoffs is just a fluke… right?

Paul Pierce filmed his arrival after fulfilling his promise of walking 20 miles to work after Celtics' Game 2 loss.

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.
