these types of players - the 40-50 per PFs - they have some potential. more than some give them credit for, but with some restrictions. basically, these kinds of players work better outside of top tier competition. when you face pfs who are also good per defenders, it just doesnt work very well. against weaker competition, they can do pretty well. they are definitely a potential option for folks who lack dominant 3 point scoring from the 1-3. however, i don't believe that 40-50 per scoring at the 4 can reach the efficiency, on average, of a top notch scorer at the 1-3. so, i feel like great teams really should not be relying on this kind of 3 point offense - they should have much better options.
that was super rambly, so i'll just say - i think these guys can work, but they are 1) not the first choice, 2) not really efficient against top tier competition, and 3) sample size is so small, and for every 1 someone finds who is actually playing like the are worth a damn, several are playing like crap. if you are trying to punch above your weight, and compensate for deficiencies, i think this is a viable route to consider. if you are a top tier team, you should be way past the point where this kind of offense has a chance of being more efficient, on average, than your lead 3 point scorers. so, a lot of this comes down to perspective.
