I'm in a hurry and don't have time to source this beyond what I've heard right now, but a couple of weekend guys on ESPN Radio just talked about Tim Donaghy hiring a prominent lawyer (I didn't catch the name...sorry) who specializes in whistle-blower cases. Their speculation was that maybe this means the scandal is far more widespread than we suspected and he'll be dropping names...possibly even NBA names.
Of course this is talk radio so take it for what it's worth. I'm sure you'll be able to find this information online as well and you can post whatever links you find in the comment section.
If this does explode into Ref-Gate '07 it should be very interesting. Anybody within sniffing distance of it has to be banned for life I'd think. We'll watch...
