As bad as Mark Blount was, there is no way Perkins was better than Blount his rookie year. The idea is absurd.
Rondo got starters minutes over Bassy and West for a good portion of 2007 before being sat and then re-earning the starting position and none of it had to do with injury. It had to do with Bassy sucking and Rondo playing better than him and then playing worse and needing to be benched before returning because of improved play. I remember that year quite well because I had a ton of arguments about how good Rondo was on this very blog.
Agreed, but in his second year he remained behind Blount aswell. You know, Blount...voted the worst Celtic ever on this blog.
Rondo didn't get starters minutes over Bassy until the team was in the tank In that year, Bassy started a CAREER HIGH 30 games. By the time Rondo was starting over West, West was playing at the 2 and was also subsequently injured.
I remember that season pretty well too

Then you clearly forgot the 9 games Rondo started while being intermittently sat because of performance and attitude problems before finally getting the start in the final 14 games of the season.

Dude I barely remember what i had for breakfast.
Still, based on that it's fair to say: 06-07 Season - Bassy started over Rondo more often? That's my point. Bassy was absolutely stinking up the joint for most of the season and still played more than Rondo, who didn't see his significant minutes until the season was in the tank, Doc had checked out, and we had like 9 active players.
I should state, I don't necessarily think this phenomenon is a bad thing, in fact most coaches are this way. Rondo was the vastly superior player that whole year, but his game was wild and instinctual, and Doc wanted to run a set offense so he went with the guy who had more experience at the professional level.
All that said, all this debate is over nothing, we all agree that:
1. Doc looks to play vets over rookies
If Johnson, Brown, Moore or Stiemsma make it onto the court it will be cause of desperation due to injuries or because they earned it with their play. That is Doc's way of handling rookies.
2. The above fact contributes to the only point I ever tried to make on this stupid thread: JJJ is therefore less likely to start at the 3 over Daniels or Pav.
Now if you'll excuse me I would continue this conversation but Im just going to go bang my head against a wall instead...
