From that reporting, he probably didn't talk/cooperate, getting released because you did a year, and and being released pre sentence is very different. Sounds like he's done. They want to start securing guilty pleas. Gunna is just a nobody in terms of the actual racketeering case.
Look at it like this, if they offer Gunna, a nobody, 5 years suspended, 1 year served, if they want to plea out Thugga, they will offer 15, with 5 suspended, or something like that.
If Thugga goes to trial and loses, they will give him something he will never recover from.
