People, you realize PP is 6'6 as well right? Daniels can play the backup 3. If you're looking for that really long or multi-talented wing that can play on the wing and play the 4 spot, those are a dime a dozen.(Posey, Odom, Lewis, Diaw, Jamison, Al Harrington, Josh Smith, Marvin Williams, AK47) If you noticed most of those players start, and have big paychecks for the most part. Those guys are really rare and aren't just running around like the 6'3-6'6 guys are. Would I love to have a long win player backing up Pierce, yes, but do I see us finding a quality one that would come cheap and willing to only play a bench role..no.
I'm really happy we got someone though, that at least is 6'5+ in Daniels, as TA, Giddens, and Walker are no bigger than 6'4.
Also he is not a restricted free agent, Indiana did not pick up his option, so he is free to go whereever he wants and sign whenever he wants. http://sports.espn.go.com/nba/news/story?id=4294765
