I don't think we need TJ Ford or Mike Bibby (although I wouldn't say no to them), but given West's injury history and Rondo's aggressive style, it is really risky to have only two NBA caliber PGs on the team (Bradley cannot see the floor in the playoffs if they want to win). So, with 3 open roster spots, I think one of them needs to be filled with someone else who can handle the point in case of emergency.
