Hopkins worth the risk if next season there is a mentality of "money is no issue." If there is space in the NIL, then it is worth investing in Hopkins to take the chance he returns to pre-injury form. If not, well then, it is best to save the money to invest in guys you know are going to be on the court.
The other thing to consider is how real Rick's 6 or 7 guy comment is. If you assume RJ is the gap between 6 and 7 and expect to return Zuby and five others (we can debate for days about who those five are) then you have anywhere from 5 to 7 spots to fill (assuming a roster of 12 or 13). With that many openings you can afford to take a shot at Hopkins and if he spends most of the time in a boot then you maybe you don't miss him too much if the other transfers are excelling.
I think this just comes down to budget constraints and if there is enough money to take a risk on Hopkins and his health while still bringing in the necessary pieces to replace Smith, Kadary, Aaron and possibly RJ. Oh, and I'm sure if RJ returns, he and Zuby will be getting healthy raises next year.
