She was responding to Gil saying Angel is a bully (strictly based on play by how she bangs in the paint), so Sheryl was saying by that token, you can say Caitlin is a bully based on how she pushes off on drives and such.
Also, while I didn't click on this particular tweet (since I actually watched this segment yesterday), I know at some point, Sheryl why trying to understand why Caitlin gets treated with kid's gloves while someone like Angel doesn't. She said she thinks she knows the answer, but wanted someone else to answer it first. You know she wanted to say her race has to do with it and why every time she gets fouled, it's national news. Gil was saying it's because Angel is seen as a bully, and people aren't gonna feel sorry for her, similar to how they wouldn't feel sorry for Draymond
