Voting C’s in 5, but noting that over the prior four playoffs, the Celtics led by Tatum and Brown won in 7 each of the three times they made it to the second round, with three different coaches no less. So while they should win in 5, they’ve clearly had trouble in Round 2 in the past. (Note over that same period, their average first-round was a 4-1 series win, like this year).
