Summers is a good sleeper pick, but Daye was taken about 15 picks too high.

Its unlikely that all three of these guys will become good NBA players, but there is a lot of potential with Detroit's picks. Daye is a guy who I don't think will be a great NBA player. Everybody raves about his skills, but after watching a lot of Gonzaga the past two years, I have to question his intensity. He doesn't seem to get after it like you want from a first round pick, and with his slight frame he will need to be aggressive. Despite his height, he will probably be more of a 3 who spots up from the baseline and outside the arc.
DaJuan Summers should be a good pro. He has good height and size and isn't afraid to throw his weight around. He is still just twenty-one, and I wouldn't expect him to be an immediate impact player. However, I can see him becoming a quality backup for a long time. Jerebko is unknown here in the US, but he had decent stats in Italy's top league. He seems to be a good athlete that could be a decent bench guy at some point as well. While this draft isn't lights out great, it does seem that these three guys should have a decent chance of helping the Pistsons down the line.
