but it is hard to answer this in general, because there are differences betwen a 100k and a 100k backup.
For example my own* Backup PF/C:
Jump Shot: strong Jump Range: respectable
Outside Def.: strong Handling: respectable
Driving: average Passing: strong
Inside Shot: tremendous Inside Def.: sensational
Rebounding: prodigious Shot Blocking: mediocre
Stamina: inept Free Throw: respectable
Experience: strong
salary: 52k
I have no big trouble to bring him even as a starter, and from skill/salary point of view he is pretty close to a perfect backup for me. He got assisted by a 35k multiskilled center, but i won't say that every 35/50 combo would work and that they are enough player like this outside for every div 1 team ... So you go higher in salary, and lower in secondarys(buying price), and you don't get a general answer anymore.
* i did it again extra for you :)
