An NCAA Tournament win would do more but I wouldn't discount what having an NBA player could do for the program, especially since Freeman seems very close to Groce and loves Akron. Having an NBA player who will likely be a willing pitch man for the program and Coach Groce is another tool the coaching staff will have at their disposal.
I also hope Athletics has a plan to capitalize on Freeman getting drafted. It should be in place already, as it now seems to be a question of when he's drafted and not if. IMO they didn't capitalize on his star power while he was here, but the past is the past and they now get a second chance of sorts.
Him being drafted needs to be made a huge f'ing deal. Billboards congratulating him around the city. A giant display with a photo of him holding his NBA team's jersey on draft night in and/or outside of the JAR. And don't wait - hang #25 in the JAR this coming season. He's the greatest Zips player ever, he's everything you want in a young man representing your university, and there's literally zero reason to wait.
I've said it before and I will say it again - if Athletics wants to be viewed as a serious program, they need to act like one. I'll be watching closely and hoping they step up to the plate with what is an absolutely incredible opportunity for them.
