Don't you drive yourself a bit nuts, banging your head against the wall and repeating the same thing into the void repeatedly? I think everyone that opens up this message board up once or more a month gets your point, you don't need to repeat it ad nauseum. Some agree with you, some disagree with you, but IMO you aren't adding value by further restating it at this point. Instead you are potentially building annoyance toward you from some subset of the board (or from me, at least).
From watching Nicholson play I think the numbers are (a) small sample size, (b) influenced by competition, (c) generated in spite of rather than because of him (he has high shooting % at 8-11 this year but also has high turnover rate), and (d) don't account for factors that hurt us down the line when he is off the floor (accumulating fouls). All that said I think he's earned the chance to play at least one stretch per game (~3+ minutes) against most opponents, as long as it's not a severe matchup issue. And against a team like Purdue, if anything it's a matchup benefit to throw him out there against Edey because it would have freed Nance up on defense, so I think he should have played probably one stretch each half, and maybe more if it was working well.
But this isn't new ground, we've covered it many times over. Safe to say that in my opinion playing Nicholson more is more of an experiment / learning experience - and due to his limitations currently, that is not the difference between us winning and losing B1G games.
