With the big announcement this weekend, I decided to look at Trent Lockett. He has 12 players to compare to, so I'm confident on this projection. Vander and Jamil have the next most comparable players at 8.
2012-2013 (2011-2012) Statistics
Minutes Per Game: 31.8 (34.9)
Field Goal Percentage: 48.4% (49.8%)
Three Point Percentage: 38% (41.2%)
Free Throw Percentage: 72% (71.1%)
Rebounds Per Game: 5.7 (5.8)
Assists Per Game: 2.4 (2.2)
Blocks Per Game: 0.4 (0.5)
Steals Per Game 1.1 (1.5)
Turnovers Per Game: 2.3 (3.2)
Points Per Game: 13.84 (13.0)
A minor increase in numbers with a minimal decrease in minutes played. If you are looking for a similar Marquette offensive player, I'm thinking DJO's sophomore year: 13 points in 29.7 minutes. A similar offensive Big East player from last year would be Shabazz Napier: 13 points in 35 minutes.
