AJ Brown concerns?

With his knee surgeries and knee issues this preseason, any concerns for AJ Brown this season? Currently, I have him as a keeper in the 12th round, but I could also choose Mark Andrews as a keeper in the 12th. Should I stay with Brown, or veer towards Andrews with Brown’s knee concerns? Thanks much!

I read reports that AJ Brown was “unguardable” in Titans camp. Keep him 100% nobody YAC’s like him
