He's a fine player but not doing cartwheels over him or TJ
a lot depends on what you're expecting from your pg. The Knicks at the moment have a fair amount of versatility. they have run plays through Randle, RJ, Burks, and pgs.
Randle and RJ in particular do a very good job, not because they're the second coming of Larry Bird or Magic, but because they're better with the ball than their defenders are against it.
So if you want an electric playmaker I'd pass on Jalen and TJ (though i wouldn't cry with either for the right price)
Thibs plays an old Celtics style where the pg (or ballhandler) is supposed to touch the paint. it's another form of spacing forcing the pocket to collapse some. So you want someone who can do that consistently (Rose can still do that)
Great outside shooting would also help. Not sure whether Thibs wants someone with razzle dazzle or a ball hog.
