Matt Barnes - Grossly overrated on this board. Barely an upgrade, ever so slightly and upgrade, on Scal. I too worry about his contributions away from Nellie.
Grossly overrated? How about grossly underrated? He's not that good of a player, but a slight upgrade over Scal? Come on. I know there are some people that overrate players on this board, but seriously... no need to go to the other extreme to balance it out. He's quite an upgrade over Scal, easily... no doubt about it.
Devean George - Good defender, good shooter, a well rounded player overall. Solid contributor. Can't be a 6th man but a good 8th man.
Okay so I've a shortlist of seven guys I'm comfortable with.
I hate Devean... I'm pretty sure everyone in Dallas cringed everytime he stepped into the floor.
Tony Allen - One of the best unrestricted free agents on the market. I'd be very happy bringing Tony back. Himself and Bonzi are two similar players in that they can't shoot but can create their offense and give the second unit a go-to option.
I want Tony Allen back myself. I'm not sure about Bonzi, though I've liked him in the past... I'm not sure if I want him playing for us at the moment. If he's all we can get, I wouldn't mind it much though. Depending on who Danny has in mind, TA should probably the complementary piece in most cases just because he doesn't take part of the MLE. Good defender, and I just like players that penetrate and try to make things happen. He'll be much better this year, I'm sure of it... how better, I don't know, but surely quite better and more useful.
Walter Herrmann - I'd be very happy with Herrmann. I haven't seen him defend small forwards enough in the NBA so I don't know what his defense is like there. On power forwards he's very good and perimeter bigs. He's also very athletic. Great shooter. Tough as nails. If the team signs Herrmann they should bring in another wing, a two guard (Tony, Bonzi, Mo), who can defend both guards and small forwards in case Herrmann can't defend them at a high enough level. I'd rather Herrmann than Boki.
I like Walter quite a bit, and share the same concerns you have about him guarding small forwards.
Kareem Rush - Restricted but I don't think Bird matches an offer considering what Indy already have on the wings. Good defender, good shooter, good scorer, good teammate. Just a very solid player
I haven't been much of a fan of his, but I'm warming up to the idea of him. We could use his 3-point shooting currently certainly, among his other attributes.
