I wouldn't place much weight into this at all. This happens all the time no matter the team, that the "practice squad" beats the starting group during practice. You hear of it happening at every level of basketball.
I have first hand experience of this happening on highly successful teams more often than outsiders would ever think it happens.
Practice is so much different than actual games. If the starting group played the bench guys in an actual game they would beat them by 20+. There is a reason the one group is the starters and one group is the bench/redshirt guys.
With that being said, as an overall team, we are just plain bad. That we don't need time to tell.
