seeing as speights left after his sophomore year let's compare the two (chuck and speights) sophomore years:
Chuck: 13.8 ppg, 6.2 rpg, 1.9 bpg
Mareese: 14.5 ppg, 8.1 rpg, 1.4 bpg
Chuck Sr year: 17/4 ppg, 7.8 rpg, 1.4 bpg
seeing as how his (speights) stats were better in rpg and bpg than chucks sr stats, it's most likely that in 2 years his ppg would have been better, too. who knows. since he left as a so the only thing you can really compare is their 2 so year campaigns and while his isn't lightyears ahead of chuck's, it is better.
