Really? No one? Wow. Is this the bubble tea guy again?
I'm going to invoke the pigeonhole principle. Every draft ever has produced at least 3 star level players, given say 5 years to develop. Therefore, there must be AT LEAST 3 players with star potential in every draft, unless you are staring at the single worst draft ever. Heck, if 50% of players with that potential reach it, then there are at least 6, etc.
Here are some historical tallies, with guys listed for recent years that definitely are considered to have star potential.
2003: 9 All-Stars
2004: 6 All-Stars
2005: 6 All-Stars
2006: 5 All-Stars
2007: 4 All-Stars
2008: 7 All-Stars
2009: 6 All-Stars
2010: 3 All-Stars
2011: 5 All-Stars
2012: 4 All-Stars (to-date)
2013: 0 All-Stars (Giannis, Noel, Oladipo, Gobert, Schroder are at least potentials)
2014: 0 All-Stars (Wiggins, Parker, Gordon, Randle, Exum, Smart, Saric, Payton etc)
2015: 0 All-Stars (Towns, Porzingis, Russell, Okafor, Turner, Stanley Johnson...)
2016: 2 maximum (!)
