Isaiah Thomas was there when the Celtics needed him, and had he never appeared in Boston, the team may not look as good as it does right now.
The Celtics owe Isaiah a debt of gratitude. He came to the Celtics via trade in February of 2015 and immediately had a major impact. He averaged 19.0 PPG in his first season in Boston - 22.2 PPG in his second season - and 28.9 PPG and 5.9 APG, while shooting 46% from the field in his final year here.
He was a major reason that the Celtics got into the playoffs all three seasons that he was part of the team, and he put the team on his shoulders when he took them to the Eastern Conference Finals in 2017.
