DRose can bring intensity to the whole team once he started to spark, just like an engine when got heated he's going to bring great performance.
I'm a DRose fan but we have to accept that there's no already spark in him. He is inconsistent for several seasons now and it's understandable. Feel sad for him that he ended up being traded for several teams. If there's a spark, then he won't be considered trading at all.
Knicks just accept the trade as maybe because DSJ doesn't really fit on their chemistry. That's the problem too why he was being traded from Dallas to Knicks. He's always acted as a leader even Luka is performing better. Maybe ego because DSJ was drafted first.
I don't think a player can act whatever he want, his job is just to follow orders from the coaching staff, let us stop speculating, we never know what's really happening inside and those trades are for the best interest of both team the fact that it happened and both mutually agreed.
