FWIW, I just heard at about 5:50 pm EST from the Pistons flagship radio station, that Billups is extremely doubtful tonight and Eric Snow is probable.
To make matters worse for the Pistons, Chucky Atkins isn't at
100% and will play but it has hindered his play the last quarter of the season and in the playoffs so the jury is still out as to how effective he can be tonight if he gets the lion's share of the minutes. Rumour is that Tayshaun Prince or Rip Hamilton could see some minutes running the point as well.
