I just don't feel too comfortable with Daniels playing without Ray, Eddie, and Rasheed at least, cause if he isn't getting to the rim he's not worth having out there.
Daniel's is certainly worth having on the court for his defense and to give Pierce and Ray some rest during the games. I think you're focusing not only one one side of the ball too much, but on one aspect of offense, which is jump shooting. You need to take into consideration all of what Daniels will bring to the team when he's on the court.
If Pierce and Ray are both in foul trouble I can think of multiple lineups that would function just fine with Rondo and Daniels in the lineup... how about RR, House, Daniels, KG, Sheed or RR, House, Daniels, BBD, KG or RR, Daniels, Walker, BBD, Sheed ... I mean we have tons of options.
Also, I don't understand this idea of Daniels as a horrible "shooter". How is a career 45%FG a terrible shooter. He might be a poor jump shooter, and god knows I don't want him taking a single 3 all season, but fact of the matter is he can put the ball in the basket. To say we need "atleast" eddie, ray, and sheed on the court to counter for Daniels shooting deficiency is blowing it way out of proportion. I mean he led rookies in FG% his first season.
