If everyone stayed, we would have Carlton, Diarria, Whaley and Akok at the PF / C position + Ried if we could sign him. If any of the first 4 were to not continue on at UConn we would have another scholarship (maybe 2) to get a grad transfer / JUCO big.
Either way, I'd rather be thin at the 5 next year and have a guy that can potentially become an impact player in 2020-2022 than pass on potential long term talent for a 1 (maybe 2) year stop gap. Whoever is on the transfer market / still available at the 5 is probably not going to be much better than Cobb or the grad transfer who broke his foot this season.
We are not a Final 4 contender next year, maybe we get into the tourney but maybe we don't. Since we don't have a real legit shot at getting back to that peak in the 2019-2020 season, we need to use it to let Dan Hurley build his system with players he can mold. Let's stock the pond now if we have the chance.
