You don't replace Bruce Bowen. At least, you don't find anyone who plays the lockdown D he does. You don't find anyone as clutch as Rob. Just like we could never find anyone to replace what Admiral brought to the table. You just have to add good players wherever you can, because you're not going to find guys to fit that same role as well as the original.
I don't want to throw out the word dynasty yet. 2 out of the last 3 is freaking outstanding, but it would take a repeat before I'd begin to discuss that. I just want to enjoy this one, because you never know when it's going to happen again. When we won in 99 I just expected the next le to come easily, because the Spurs were the best then, so why would things change? Things did. Sean got sick. Tim got hurt. Tim had to learn how to pass out of the double the hard way once he got his first le. David started aging. Phil Jackson taught the most talented team in the NBA how to play as a team. Kobe Bryant became unguardable.... and then, 4 years later when none of us was expecting it and everyone was either too young or too old, this team comes together and David retires a champion with a monster performance in game 6. Next season Spurs are on a 19 game win streak in the playoffs, and then go cold and 0.4 happens. The team is reborn with a vengeance after a couple of offseason tweaks, and looks unbeatable. But it almost doesn't happen. The franchise goes down on Rasheed Wallace's foot. But it does happen.
Don't take these for granted, Spurs fans. Enjoy this le. It may never come again. All kinds of things can happen. With our core still young and locked up long term I'm guessing we'll see another parade or two down the Riverwalk in the coming years, but let's never count our chickens before they hatch.
