i'm interested to see if you can project the top 10 rotation players for 2020 if hurley can bring in both a guy like cliff, and towns. then you'd realize how stacked the roster is and why towns is worth the risk/reward. his presence would raise the ceiling all the more and his absence would barely put a dent in the floor. no more than 10 guys should get meaningful PT anyways.
Wasting a scholarship is about the opportunity cost of not that year, but the lost development time. In 3 years, do you want a junior in that scholarship or a freshman plus 2 years of a guy who suited up a rusty 6 games total?
