Look at the ones that didn't play and you can figure out why:
Xavier Simpson | Michigan | No. 67 overall, No. 13 PG - Good luck playing over SR Derrick Walton Jr 4 year starter
Markell Johnson | N.C. State | No. 59 overall, No. 10 PG - Good luck playing over the #3 PG and #7 overall player in your same class
Payton Pritchard | Oregon | No. 54 overall, No. 9 PG - Still had 7.7ppg on a Final 4 team
Ty Jerome | Virginia | No. 44 overall, No. 7 PG - Good luck playing over SR London Perrantes, leading scorer
Cassius Winston | Michigan State | No. 34 overall, No. 5 PG - MSU was full of talent, just didn't live up to it
Tell me how any of those 5 players fit in to the same role Lindell is coming into. The other guys on his list were the 5 that averaged 9.9-13.2ppg. You've seen that link posted a few times but I don't think you've read it once.
"But the top-tier players who produced in their freshman campaigns found themselves in situations of need. Moore had a usage percentage of 26.8 percent at Cal, Howard's was 26.7 percent at Marquette, Carr's was 24.3 percent at Penn State, Fisher's was 20.9 percent at TCU and Cowan's was 20.1 percent at Maryland."
So comparing to the guys who didn't have some elite player in front of them, Lindell should be 10-13ppg.
