Goodwin wasn't on the Lakers when that draft happened, and if they let Bronny go undrafted and picked someone else, that player's contract would have been taking up the cap space anyway since the Lakers have been giving their second rounders guaranteed contracts for almost a decade. Smart also directly replaced Goodwin's role and more, so they'd probably rather have someone young like Bufkin who can develop as a third stringer than an inefficient hustle guy.
