Not sure I agree with that comment. I would say quite a few things have already been answered:
Lost Sherfield, Cortes, Noland and Bam from the guards' group that contributed at some point last year.
Replaced with McCollum, Darthard, Soares and Cooper (obviously don't know anything about what he brings to the college game).
Add those 4 to Los and Oweh and you now have 6 guys to rotate in for those 3 spots.
Lost Hill and J. Groves at the 4. Have not replaced any of that production to this point that we know of. Could go bigger here with a more traditional low post with what is already on the roster or really need to add more of a stretch 4 starter from the portal.
Back-up 4- Possibly Cole? Again we don't know really what he brings to the table at this point.
Lost T. Groves at the starting 5.
Replaced with Hugley- depending on what your goal was here, I would say it's an upgrade in regards to toughness/athletic ability and inside scoring and a downgrade in regards to shooting from the outside.
Backup 5 is still covered by Godwin and possibly Keita or Northweather
In today's world of the transfer portal, I think depth is going to be a crapshoot for most teams consistently each year until the season starts and you see what you have and hopefully you hit on a lot of the portal and freshmen you bring in.
So with that said, OBVIOUSLY the glaring hole is the starting 4 spot but I don't know if that means they have more questions than answers at this point. Just my opinion
