Do you think Derrick Rose and Kevin Durant will be consistently great throughout their careers? are they?

future Hall of Famers? and when I mean consistently great, I mean as in if will they be high or great scorers throughout their career, for example, Kobe is getting old and he still is a great, dominant player, he has been a consisten scorer throughout his career, for example in the late 90's and early 2000's, the best scorers, who averaged a lot of points per season were Kobe Bryant, Tracy McGrady, Allen Iverson, and Vince Carter, but out of all those 4 players, Kobe has still remained dominant and consistent, Iverson, Carter and McGrady started losing it as they got older, up their in age, but Kobe hasn't lost it yet, he still is a very consistent scorer. So do you see Derrick Rose or Kevin Durant being consistently great throughout their careers? or will they eventually falter like Allen Iverson, Tracy McGrady and Vince Carter?
