I understand that and it is a reasonable request. When you say someone isn't contributing are you saying not scoring? If that is not contributing then only maybe Braden and Zach contributed on offense with a small spurt by Mason in the first half. No doubt someone or a few or all need to score depending on a perspective, but does that mean someone not scoring is not contributing on offense?
There is no correct answer, but some would say that having a shooter just standing in a spot ready to shoot even if he doesn't shoot is contributing to the offense since it affects the D. Others might see a PG ...say Braden not score much against IU (I thought he was excellent other than his shot didn't drop) and say he isn't contributing much offensively and others might say Zach didn't contribute much offensively in other games or even Lance today. I think you can contribute on offense without scoring, but somewhere at some time...someone must score and preferably if possible a lot of players score.
So Fletch contributes offensively even if he isn't scoring...maybe or maybe not as much as another but he is "a" focal point of the D. Matt is looking at a "team" effect that sometimes blurs individual appraisaIs from others. I know what you are saying...it is just hard to put a definitive rating on a player that doesn't score as to how much he contributes. Same with a player doing things he shouldn't missing a lot of bad shots or turning it over, late on screens, poor screens, not handling it much, ball sticks, and yet scoring. Matt's teams don't have the same individual play as some teams and therefore is more difficult to appraise in how much a player contributes, but I fully understand when a player isn't scoring the flip side of that dependent on whether that player is a focal point for the other team or just a guy now playing that is not a focal point...and to your point it is also possible the non focal point could score easierand who knows how he mixes with others. NO easy answer in defining who contributes on offense.
