Bulls made a signing last night, inking a deal with guard Isaiah Canaan.
It's reported as a 2yr, $2m deal, but that's essentially the minimum for a player of Canaan's service (3 years) and there's no reports on whether it's a guaranteed contract. Update: Thanks JSlakov in the comments, KC Johnson is reporting the 2nd year is a team option, implying the first year is guaranteed.
That's a pretty significant detail, as he'll be battling with Jerian Grant (guaranteed) and Spencer Dinwiddie (not) in training camp for a backup guard spot.
