For him to take the deal they would have had to sweeten in a little and remove his biggest concerns.
I mean he did beat them.
Not totally but of there were a belt it would be in his corner today.

I get most wanted to convict
However, he only needs one juror on his side to win again.

They very rarely if ever come back for a 3 trial
Especially becaus they did not want to try it the first time and if he can get one juror a second time.

The feds need all 13
Joey needs 1

While.house arrest appears attractive
I believe he is more worried about the next case which will no doubt have him facing 20-30 years.

I would tho k given the option to pick either
House arrest or the feds not being able to use the case against him in the future
He would choose the 2nd part
