I'm just saying it's not obvious or a no brainer that Kaku leaves. Kaku excelled under Marsch, and I would guess Struber will play a similar style. So it wouldn't surprise me if Kaku can get back to or at least closer to his 2018 level.
If RB is going to lose $2-3million on Kaku, why not just keep and play him? Struber just left a club because he didn't have enough attacking options. I think Kaku only goes if they have his replacement lined up. Like when we traded Sacha to make room Kaku. I guess if Clark is capable of stepping into Kaku's role, since he'll hopefully be on the roster, moving Kaku at loss would easier.
Also if Kaku goes, does RBNY spend $$ to bring in a player who would be transitional to handing the job to Clark? Hes looked great at the USL level but thats a big ask and risk to take without a slightly more experienced option.
Depends on where Struber sees Clark fitting into his system as well
