Was Doc's team underachieving? Based on talent level, I'd say no. With Mchale, he did underachieve based off talent level.
Talent? TALENT??? OK. Click this LINK. That is Houston's roster for the 2012-13 season. Look at those names. Does that roster say Western Conference playoff team? Sure, in hindsight it does. What that roster really says is D-League with a couple of veteran journeyman. We used 14 players with 2 years or less of experience. Western Conference. 45-37. Team upheaval pre-season and then mid-season. No problem, right?
So, then the playoffs come around and we are facing the #1 team in the league with the #1 ranked offense and #4 ranked defense and the 2nd best player in the world.
We played that series without a PF and with a mid-season rookie at PG. We lost games 2 and 3 by 3 points a piece. That is a one possession game. We proceeded to win the next two, before falling again. Yes, I recall Westbrook went down and that matters. We were still huge underdogs. Our bench was Greg Smith, Carlos Delfino, Francisco Garcia, Terrence Jones, and Aaron Brooks. Underachieve is so far from the right word.
I've gone into detail multiple times about the Portland series and why it was not a massive failure. Was it disappointing? Of course. That doesn't mean that months later we, as fans, should still harbor emotion-based resentment that skews our ability to see objectively. Portland was a very good team, that came into the series hot, got tons of good bounces, ran into an ice cold James Harden, and still needed two buzzer beaters to win the series. Underachieve? Whatever. I wonder if everyone holds themselves to the same standards they apply externally....
