agreed, probably mental. i tore my ACL and it took some time to get over the mental part, and at that time i was at best second team all star basketball player at tropical park (not to be taken lightly).
that backfield is elite.
i've seen him practice and do drill 10 feet in front of me. he is nursing the knee, not really a limp, but you can observe that he is cautious with it. not sure if it is mental or physical. i would not expect him to play 8/24, but you never know.
