To Loose Cannon, you may be right about TA; however, keep in mind that even if Rondo, Allen, and Pierce only averaged 32 mpg each, that'd only leave 48 mpg to backup the 1, 2, and 3 spots. I think Eddie and Daniels could each play 24 mpg and cover all of our bases without overburdening anyone. Foul trouble could force Doc to use someone else at times, but I see no reason why House and Daniels can't cover us at the 1-3, even during the regular season.
To Fafnir, I agree that Daniel's lack of shooting is a concern; however, the C's didn't do horribly last year with Rondo and TA on the court from a spacing perspective. There were certainly problems with that lineup (namely TA dribbling the ball of his feet or throwing it away), but Daniels should hopefully mitigate those problems. Plus, he'll likely get the bulk of his minutes with House and/or Wallace, vastly diminishing the spacing issue.
And another issue in general to consider: a lot has been made about the offense going "stagnant" when House was running the point in the past. While I am fully aware and totally agree that Eddie is a deeply flawed playmaker, let's also keep in mind the circumstances he often played in. In my opinion, in general, Doc has done a poor job rotating subs in, often leaving House with just one starter on the floor who Doc runs isos through. To contrast with that, think of 2008 when House would play with the lineup of Allen, Pierce, KG, and Posey. That lineup certainly wasn't stagnant offensively. Furthermore, the problem of getting Eddie some firepower to play with was further exacerbated last season as the absence of KG led to him playing even more with limited offensive firepower around him.
What's my point? Simply that this season with improved depth, even if House (or Daniels for that matter) is asked to bring the ball up the court, the offense shouldn't be nearly as stagnant as we should almost always have 2, if not 3, offensively potent options on the court with him, whereas in the past, we often only had 1.
