a lot of the matchup depends on whether Timelord and Lowry play. If they're both available, I give Boston the edge at PF with Al but not with GWill over Tucker. Also think C becomes more of a draw between Bam and Timelord as opposed to Bam vs Al (edge to Bam). Lowry/Smart is a wash but Smart is better than whoever Miami would start in place of Lowry.
also, Timelord's availability moves Grant to the bench which improves the C's bench where I'd give them the nod. Lowry pushing his replacement to the bench doesn't improve it nearly as much. without either of those 2, Miami has the better bench. With them both playing, C's have the better bench. now if White could provide some consistent scoring off the bench, it's Boston's bench by a healthy margin.
