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.
If he has no spark for sure he is out on the NBA and look at his stats he contribute decently even though he have limited minutes on his plays. Also every player have a role and it's just he is not the first option in terms of offense that's why we cannot see him do well compare on his bills days and sadly those past injuries really hurt his career since by now he cannot get back on his foot to get a bigger role on his team.
