Up until this past year, UCONN has almost always had a top post player in combination with an exceptional forward to help shoulder the load.

2017: lacking true big, 5-11 Williams played big and 6-1 Collier
2018: 6-6 Stevens, 5-11 Williams, 6-1 Collier
2019: lacking true big, 6-1 Collier, 6-1 Walker, no true big getting 20+ minutes
It's no coincidence that the rebounding margin was significantly less during the 2 years where two years UCONN lacked a big post presence playing 20+ mpg. If ONO develops, UCONN will be fine. A combination of ONO/Walker is a formidable front line. Especially when your backcourt is Williams/Bueckers. If ONO doesn't develop, it could spell trouble for UCONN.
