I vote for leniency, particularly in agreement with Seble's point that it's better to have a player 100% where he shouldn't be than less than 100% where he should be. I remember how much it drove everyone crazy when the 32-8-8 Jordan was only 92% at the point. The same applies to other players, just my opinion.
For example, does anyone doubt that Lebron has the skillset to play point guard if called upon? Just look at the fourth quarter of virtually every game he's played, particularly in the playoffs. He set up the offense because he WAS the offense. Mo, Gibson, and the crazy guy, whichever one of them was in the game at the time, became wing spot up shooters, not point guards, as Lebron broke down the D and made decisions. Those guys might have started at point, but Lebron finished it.
Besides, it's part of the fun of What If to be able to put together amazing combos, within reason of course. If Don Nelson was a What If GM, you know he'd be lobbying to have some 6'3" guy play center. In any event, if the desire is not to have to make a bunch of individual exceptions, I wouldn't mind having guys be able to play a wider range of positions than they might otherwise deserve.
P.S. Seble, just curious, are Rodman and Moses still programmers for WIS? I'd always wondered what they were doing in retirement.
