Cmon Giddens or Walker cannot defend the four. You really believe rookies can come in and understand and execute TT defensive schemes better than someone who has been here since day 1 of a championship year. My feeling is that Giddens or Walker would look alot like Gerald Green out there(totally lost)IF Posey leaves giving Scal 5-10 minutes a game for the first half of year will not be a problem and maybe give him some trade value.(zero right now)
I am on the sign Posey (nearly) at all costs side; however, if he does leave, it might not be the end of the world with Giddens. While I wouldn't say Gerald Green would do well here, he would do much better than he did last time around. Why? Because, all he'd have to do offensively is spot up for threes on the weakside.
The bust who might have actually taken Posey's place the best might've been Kedrick Brown. He was a decent shooter and had excellent athleticism to play defense. Giddens by most accounts is more polished than Brown, has great athleticism, can shoot fairly well, and plays some defense.
By no means am I suggesting that we don't sign Posey; Giddens cannot provide the intangibles, the heady plays, and respect accorded to vets by officials. However, if he walks, he may be a better option than some free agents.
