Well, it sounds like the problem is not with Daniels, it is that the C's still need to bring in another rotation-quality wing. I agree with this. I think if the C's signed a SF like Moon or Barnes, they would have had to then get a decent PG. With Daniels, the PG is less important, but they now need to find a SF who can pick up minutes as the 8th-9th man.
The fact is, the C's needed a player with Daniels talent-level to be the first wing off the bench. Whether it was more of a SG or SF was somewhat irrevalent, they just needed a 7th man. Now they just need to fill out the rest of the roster.
But Chris, where is this "SF who can pick up minutes as the 8th or 9th man" really going to find minutes? There's no way Pierce or Allen are going to average less than 34-36 mpg. And that average will likely include blow outs, where they'll play less; so in close games when who we had on the bench would actually matter, they'll likely play more. Daniels played 31 mpg last year. There's only 96 mpg at the 2 and 3 spots.
So while I'd agree a 2/3 with range would be nice, I don't see where he's going to get minutes. Furthermore, if we gave this imaginary 2/3 with range minutes, given who is left on the FA market, I feel it'd probably be more of a downgrade in talent over anything he could offer.
As for how Daniels fits in, I don't think we need to worry about it a ton. First, I think House is fine playing backup 1, and this is from someone who has railed against him for the past 2 years. Unlike two years ago, we know Rondo is an elite PG who can play 35-40 mpg. While I don't love House handling the ball, given how good this team is and how much Eddie brings to the floor with his range, I think we can get by with him, or PP, or Ray, or Daniels bringing the ball up the court for 8-13 mpg. Since that's the case, I don't think Daniels' lack of range is that big of deal. Likely, he'll often be on the court with a unit of House, Ray/PP, KG, and Wallace, so the other 4 will be more than capable of knocking down long range shots. On top of that, I think the sheer fact that he's good will be an upgrade over anything we had last year. Sure, he isn't a threat from 25 feet out, but the fact that he's a threat from anywhere makes him an upgrade over any 3 we had last year.
