Depends on the matchup, obviously.
I think the Bucks are going to be tougher than some expect. GA is an NBA darling - he's going to get calls like a superstar in the playoffs and I wouldn't be surprised if he averages > 9-10 FT attempts per game. He gets to the FT line far more than anyone else in the league at 8.7 FT attempts per game besides Harden (who "earns" 10.2 FTA per game - for reference, LeBron is at 6.5, and the next closest is Anthony Davis at 7.9). If we were healthy we'd crush these chumps but obviously this isn't the case. Middleton is a solid player as is Bledsoe. Their bench is lacking but so is ours. I'd expect it to be a hard fought 7 game series.
On paper, Miami is the best matchup. An overachieving team in the regular season that isn't constructed for playoff success because they don't have superstar/upper echelon star talent. I don't see individual matchup concerns. Good defensively but like the depleted C's roster goes through offensive lapses. We can win in 6.
The Wizards may have the worst record of the bunch currently but they're probably the least favorable opponent. Their core has continuity and despite how bad of a coach Brooks is they present clear matchup problems at both guard spots. Otherwise I wouldn't be sweating it.
I won't be too disappointed if we lose in the first round given our injuries but I'd love to see us advance to the second round at minimum as a true test to our future core, Tatum and Brown. I'm really looking forward to how they both respond to the upcoming challenge.
