Giddens has a decent 3-point shot and it'll only get better with NBA shot-coaching. He shot like 60% from the line but 33% from trey land. I figure in a year, with his technique tampered with ever-so-slightly, thats like 70% and 38% from trey. In fact, I bet he clips 40 from behind the line (if he stays healthy, out of trouble, with the team) just because we've got good 3-point shooters and that is contagious.
Walker is going to be able to shoot the 3 eventually too, hell, he might already be well better than the 30% he put up his last year in college. He's been hurt and basically just been shooting. Plus, once a guy who used to rely too heavily on his athletic gifts gets hurt they tend to tie up loose ends on the finesse end, I'm sure he ends up being a good 3-point shooter if he stays healthy and in the league. Hell, he might even end up as athlete-turned-gimmick-3-shooter in 10 years for all we know.
