I could see another combo guard who can play either point or off ball. I'd be surprised to see another true point though after Long and Morris.
It's a bit early to know for sure, but I feel like Long and Morris could both be considered combos since they seem to both be able to score... And therefore maybe a more "true" PG is needed? Who knows, I'm thinking out-loud. Can't go wrong with a bunch of guys who can handle the ball AND score.
It's also interesting that (through Matt Thomas) Hoiberg has indicated that he thinks Thomas can play some PG. So maybe the idea is to have a lot of backcourt flexibility. As always, most of these D1 guys look good running things in HS. The creme rises to the top at the next level.
Also - a note about Lewis. As I look back through twitter feeds, he and Morris seem to be pretty good friends - plenty of chatter between the two.
Finally, If anyone is counting, that's three '13 "PGs" from Flint that we've been associated with: Morris, Watts, and Lewis.
