A caller to the FAN just pointed out that a ball was thrown onto the court during a Detroit possesion. The announcer praised the refs for not interrupting the play, which was going nowhere. I was at Shea and didn't see it, but I'd be interested in thoughts of those who did. Did the refs do right, or was there danger to the players that shoud've been eliminated witha TO. Keep in mind that doing so would've given the Pistons a mulligan.
