And there are still guards available at the juco level, in the portal, and from overseas. The coaches are probably looking at what's available.
One other possible source to consider... the closure date for the transfer portal has passed., but there are a couple exceptions, such as for players on a team that has a coaching change. Michigan's coach just left, and although I don't see Bradley being a likely contender for any possible transfers from Michigan, there is a possibility Michigan might hire a successful mid-major coach, like they did with Dusty May. If that happens, there could be some new names emerge.
