Well I've only been playing BB for two seasons, but I've had pretty good success in the draft so far:
Season 15
Round 1: Garfield Jacob
http://www.buzzerbeater.com/player/19239363/overview.aspxRound 2: Donnie Anderson
http://www.buzzerbeater.com/player/19239352/overview.aspxRound 3: Bryant Swimm
http://www.buzzerbeater.com/player/19239366/overview.aspxSo basically I got an AS potential player (ok), the only 18yo 5-potential player in the draft that year, and a superstar potential 18yo with my 3rd round pick.
Season 16
Round 1: Paciano Carino
http://www.buzzerbeater.com/player/20742032/overview.aspxRound 2: Jay Munoz
http://www.buzzerbeater.com/player/20742053/overview.aspxRound 3: Bruno Miller
http://www.buzzerbeater.com/player/20742059/overview.aspxCarino was easily the best prospect in the draft, at A+ grade HOF potential 18yo. Munoz also had an A+ grade, but low potential. Again I got randomly lucky with my 3rd round pick and picked up a superstar potential player (ironically there was still an 18yo HOF available in Moses Bond
http://www.buzzerbeater.com/player/20742061/overview.aspx, but that can't be helped, and his skills were so low I would never have found out his potential anyway. All in all, 2 drafts, 2 5-ball potential players, 2 high 4-ball with late-rounders, and two mid-potential with good starting skills. Beginner's luck, hmm? That plus apparently no one else in my league can draft.
