Atlanta gave us a huge run for our money in the playoffs last year with Hortford and Pachulia (mind my spelling) out.
Who do you thing was the biggest reason for that?
Joe Johnson? No way, he shot them out of games as much as he shot them in.
Teague? No. He was solid, but not dominant.
Josh Smith was an absolute beast, and he was single handedly destroying us in every facet of the game (scoring, rebounding, assists, defense). The guy is horribly underrated in a league where people frequently considers Pay Gasol, Kevin Love, Tim Duncan and Kevin Garnett the best PF's in the league - in terms if overall production Josh Smith is at least a match for Gasol, Duncan and KG at this point in their career, and I'd take him over a "play no defense" Kevin Love any day of the week (and twice on Sunday). Plus he is young and incredibly athletic.
Smith is as much an improvement over Bass as Jason Terry us over Keyon Dooling. Bass is an elite midrange shooter with great work ethic, but is average or below average in every other way -he really is more of a very good bench player then he is a perennial starter...but he does ok for us because he fills a need.
Smith is an all-star PF. I will guarantee you right now that hell he an all-star this year. He's a top 5 PF in the league without question, possibly top 3 as an overall player who does a lot of everything. He's kinda like a swiss army knife player - like a Rondo at PF.
I'd give up anyone not names Rondo or KG if it meant a chance to get Smith.
