The more I think about it the more I believe that Hurley's use of the transfer portal was brilliant. He got good veteran players, who have either 1 or 2 years of eligibility, and each of them brings a different skill set that can be used in different situations and against different lineups. They are all team players and understand that their roles are to provide juice off the bench. All of them have been good at different times, but the true surprise of the bunch has been Joey C. He was advertised as a 3 point shooter but he is more than that. He is a crafty shot maker and clever passer. He also has hit some crazy off balance shots. But all of these transfer portal guys have given the team a lift at different times.
There has also been an intangible element in UConn's success, which is that all of the pieces work together. The team seems to have remarkable connectedness on both ends of the floor. Usually it takes time for transfer players to adapt to a new system and new teammates, but it seems like each guy had a well defined role from day 1 and came in and executed that role. They work well with their teammates and seem to understand what they need to do to help them. You don't always see this with transfer players. Hurley picked his guys really, really well.
