Can't argue with that, unless they're convinced that either Giddens or Walker will step up (and I don't think they are). I'm more concerned about them adding another body up front, though. Scal's still around, too, I'd rather he get his minutes at the 4 but he can spell Pierce a bit, too. If they bring back Starbury or sign Ty Lue, you still have Eddie House backing up Jesus at the 2 and Scal at the 3 for those nights when Daniels is out.
So, yeah, sign another wing if you can at the minimum - but I think the first priority is sorting out the 4th-big man and the second priority is figuring out who's playing behind Rondo.
