That's the thing, I think rebuilds are usually better when you try and supplement the roster with some great proven players and try and stay respectable. This is just speculation, but I think it can be demoralizing for young kids like Vladdy to come up on a team that just gets beat down the majority of the time.
I know San Diego has been crap for a lot of years, but I kinda like how they're going forward with their rebuild now, a mix of great talent via free agency mixed with the young kids rising up.
