In terms of what is going on with Jozy, I think it's pretty safe now, post the DDT (“Dwyer Debacle Trade”), to say Jozy is almost certainly being bought out, and whether TFC is handling it “correctly” is impossible to judge from the outside, we don’t know what the communications or negotiations really might be.
Suspect there is some sort of potential opportunity for creativity somewhere before Feb 26 that depends on Jozy finding a new home, and whether he is at camp or not is a small piece of the puzzle. Honestly, he cannot afford to get hurt now, if he is looking for a spot, and it may be as simple as him not wanting to take even a small risk of pulling his hamstring or adductor doing wind sprints.
