Webber was one of the best passing PFs ever, so that will probably stop the Webber comparisons. In his peak passing season, Webber had a 25% assist rate and 12% turnover rate. KG actually had a better peak passing season than Webber (27% and 12%), but wasn't nearly as consistent. Webber was high teens in assist rate throughout his entire career, while KG usually stayed in the low teens.
Kyle Singler's assist rate was 14% as a junior and 9% as a senior, and I'd expect Giles to be significantly below those numbers, which would put him a completely different category of player from Webber, though he could be close to KG.
At KG's rebounding and rim protecting peak, he was a 30% defensive rebounder, 9% offensive rebounder and 4% shot blocker, with a 5.0 DBPM and 92 defensive rating. If Giles gives us the college equivalent of that - something like 25% defensive rebounding, 12% offensive rebounding, 6% shot blocking, 6.0 DBPM and 80 defensive rating, it's hard to see Duke failing. Those are numbers that have a decent level of consistency throughout the season, unlike shooting accuracy and most other offensive stats.
