Celtics sign Daniel Ochefu (likely for just a couple days)

The Celtics filled up their 15-man roster for at least one day on Friday, announcing they have signed center Daniel Ochefu. The 6-11 big man played in 19 games with the Wizards as a rookie last season and was waived by Washington earlier this week.

Boston signed him Friday likely with the intention of waiving him in mere days before the start of the regular season. Why bother signing him then?
