Not sure about most talented teams, but my top three most disappointing Houston sports moments:
1. 1986, game 6, with Scott set for game 7.
2. Kevin-fucking Brown in '98, in the travesty that is the 5-game series after a 162 game season
3. January 3rd, 1993. The Buffalo Bills.
Best moments:
1. Bluebonnet's homerun
2. Oswalt closing down Busch, and going to the WS after being at the Lidge-Pooholes debacle the game before
3. Mike Scott's no-no
