My first instinct is to say Ollie ought to take the best players he can get. A bird in the hand. At first glance, that would seem to solidify his status as a competent recruiter in spite of only having a 1 year contract.
But Ollie's smarter than that. He seems to be shooting really high at several kids (Parker, XRM, etc.), and if he lands even one of them, IMHO it pretty much guarantees he's the permanent HC.
At that point, I'm not sure what Manual would need to see from a coaching perspective for games this year. Building a successful college program is 60% recruiting, 30% developing them in practices, and 10% game time coaching. By that I mean if you have enough talent and develop them well in practices, you will make your fair share of sweet 16's etc etc. It takes an extra special brilliant mind to take an underdog to a NC like JC did at least twice.
Maybe you could argue with the percentages I used, but IMHO recruiting talented kids is the most important aspect of putting winning teams on the court. The more I see and read about Ollie, the more impressed I am - he seems to be the complete package and the real deal.
