I personally see the recovery from Covid as a much bigger deal than the lack of depth. I am, of course, heavily influenced by my own Covid experience: it was super easy, 1 day of feeling fluish, one day of feeling a bit crummy, and feeling normal after that. Except I felt tired super easily, for like 3 weeks, doing very meaningless stuff.
The depth problem is real, of course. But we still have 7 on rotation, the magic number for me to be able to sustain being competitive. One interior and one exterior player off the bench.
On top of this, it's not like we are going up against super healthy teams. Or teams that, while healthy, have a deep rotation. I don't want to go into a rabbit hole of digging up who is injured in other teams. Or what teams, just never rotated more than 7. But, from memory:
1) Indiana - 2 starters were out, 1 is back, yesterday used 29 bench minutes
2) MSU - Hall has played very little, still rotates 3 players
3) Minny - top scorer is out, used 2 players off the bench yesterday, one for just 5 minutes
4) Rutgers - Really only heavily uses 1 bench player, not deep
5) IL - using 2 players heavily off the bench, not deep
6) IA - using 2 players heavily off the bench, not deep
7) MD - using 2 players heavily off the bench, not deep
8) WI - using 2 players heavily off the bench, not deep
9) UNL - 2 injured
That leaves, with minimal problems or a having a deep roster use:
1) Purdue
2) MI
3) PSU
4) OSU
This is a superficial analysis and there's probably stretches there. But my point is that, yeah I'd rather have Roper and Hunger available, but this is what (close to) what every team is going through and goes through every season.
