SANTA CLARA — Kentavius Street, a super-strong defensive lineman, is among the 49ers’ great personnel mysteries for their 2019 comeback tour.
Thursday, the redshirt rookie put his right hand in the turf, lowered his hulking 6-foot-2 frame and slammed forward into the blocking sled while shuffling to his right. Then to his left. Then again to his right.
Shuffling is the key right now. He is debuting in practice this week, having been relegated to the side field all year to prepare his reconstructed right knee, which is wrapped in a black, extra-large brace.
“My nickname for him is ‘Baby Hulk,’ ” defensive tackle DeForest Buckner said.
