This much is certain: The Celtics are going to need Holiday at his best come the postseason and that journey through June. Anyone who saw Donovan Mitchell drop 41 points on the Celtics’ heads last Friday — including 26 in the second half — knows that the well-rounded Cavaliers are as legitimate as their 50-10 record suggests.

“I’m not gonna lie, I didn’t really hear of the term mallet finger until people were telling me I had mallet finger,” Holiday said before the Celtics hosted the Denver Nuggetts at TD Garden. “They just told me that I broke my finger.”
