I feel like Murray can affect the game in many more ways that Horry did, Horry was decidedly a 4man, Murray has guard skills and I think is going to get the bulk of his minutes at the 3.
He can dribble the ball up the court on the break and utilize the 'eurostep'.. He's much slipperier, hes got an idea of how the defense wants to play him and the patience to wait for them to overcommit, n then he changes direction last second to open up a quality look.
When a smaller defender is switched onto him he can back him down into a dropstep going either way...
When he catches a defender biting on his shotfake from 3pt range he can take it all the way to the rack whereas Horry more of a 1dribble then pullup type of guy. There's plenty of plays where Murray gives you a fake on the catch, then dribbles, then fakes again, on the move, to open up a good angle/look for himself in the lane.
I think Murray has a good feel of where the help defense is coming from and how much time he's got til it arrives, which played a big part in his being so consistent putting up monster statlines. He's got good instincts on when to leak out and 'cherry pick' aswell.
He catches everything.. You obviously have to have a really good set of hands to put up those kind of stats on such few turnovers.
Also just with his handle, Keegan Murray is no stiff, he can get low while driving the ball.. He's got a better first step..
Keegan Murray can catch the ball, shot fake, drive 2 dribbles, then crossover to the opposite direction to create big space and then hit the J..
He's got the step-back J in his repitoire. IDK I dont think Robert Horry is a very flattering comparison, they are similar size and some of the things that Horry was good at so is Murray, both have a solid hook shot and are solid defenders with good instincts for passing lanes for example but I just think we're in the 2020's here, the players are practicing more advanced moves at younger ages, this is the era of the stepback jumper Steph Curry a pedestrian sized player rules this era, Horry was from the days of Shaq and Olajuwon, and that Murray can give us much more in many aspects of todays game.
There's an aspect of the game where your asked to stack actions one after the other very quickly and Murray has a very advanced even calculated way navigating thru that, there's really a mountain of footage to demonstrate that.. I think of Horry more as a complimentary player who's game excelled in orbit of players like that.
