No thanks...
We are already way too deep in the 6'1" - 6'8" category with:
* Rondo
* Dooling
* Terry
* Lee
* Bradley
* Pierce
* Green
* Joseph
Considering how stacked our backcourt is, we are already going to struggle to find minutes for everyone once Bradley comes back. If we get injuries to Perce or Green, then Lee and Joseph can both play minutes at the SF spot.
I don't see the point in signing any other < 6'10 players unless:
1. They are versatile enough to play multiple positions
2. They are Ben Wallace
On paper Pietrus may be less 'efficient' then Barnes but he can play SG or SF equally well on both offense and defense, he is a good locker room guy, and he has the athleticism to run the break in what I think is going to be a high octane offense this season.
Same can be said for Marquis, who's a great locker room guy and as versatile as a swiss army knife. Quis is a good ball handler, a smart decision maker on offence, a solid rebounder, a solid passer, and a capable scorer on dribble penetration and from midrange. He can fill in at every position from PG to SF and he'll never complain abot minutes.
Barnes at this point is his career is purely a defensive presence and a distraction. Like Pietrus he's an inconsistent shooter, but unlike Pietrus he's not athletic, not a good locker room presence, and not very capapble of playing the SG spot.
The only other guy I can think of that I'd like to see here is Tracy Mcgrady. Like Quis' he can play every position from PG to SF. He's got size, good handles, a nice passing game, he's a good rebouder for a SF and he's got a high basketball IQ.
Aside from these three guys, I'd be looking for another big (Birdman, Wallace, etc) with some toughness who's not afraid to bang around inside.
Last season KG we often had to pull KG back in the game before he got the rest he needed because out bigs weren't able to protect the paint while he was out. Melo has tons of potential and could be a surprise, but he's unproven and could just as easilly be a flop. Collins is a mediocre rebounder, will struggle against quicker bigs like Amare and Bosh. Wilcox and Sullinger are both question marks health wise, and neither is a natural Center.
I don't HATE the idea of signing Barnes because high energy hustle guys that play defense never go astray - but I think thre are others out there who would be more fitting. Plus out track history with guys that have mental/maturity issues (Big Baby, Delonte, etc) has not been great.
