Thanks for bringing this up. I hate it when people don't bring this up, or use it as an example for big name free agent signings not working out. That was pretty much one of the only seasons I was happy with the free agent signings that the Spurs made after winning the Championship the year before. If only Tony Massenburg could have come back, then I would have been 100% satisfied and happy with that off-season.
I always want the Spurs to reload after a Championship and I thought they had a great off-season there. Some people say that it was a failure and it didn't work out, but I disagree completely. As far as I'm concerned, that off season was a success and that team was the best team in the NBA. Definitely should have won the Championship and I'm still pissed about it anytime I see footage of Miami celebrating.
There's so many things that ed the Spurs over. Pop going small, Pop playing Van Exel over Beno when Van Exel clearly didn't have it, the horrendous officiating in the Dallas series in the 4th quarters of games 3 and 4 on the road with critical bad calls that fouled Tim and Manu out when they were both dominating the quarter, Tim having plantar fasciitis (playing through it and still playing well), Manu's foul etc. That team was definitely the best in the NBA that year and they should have won it. That is a definite championship that was left on the table IMO.
