Not that I disagree with you here--I've made the same argument myself--but I've always been troubled trying to determine in these situations which is the chicken and which is the egg. Was he shooting better because he was getting more shots, or was he given more shots because he was shooting well? Did he play better because he got more minutes, or did his playing time increase because he was playing well?
Taking it further, isn't this the crux of the "player showcasing" argument? If a team has a player they want to deal, can they increase his value by increasing his minutes and role, thereby facilitating improved play? Making this Blazer-centric, if Rudy really does need to be traded, would this be our best tactic for him (and Webster?), making him more valuable to potential off-season suitors?
Somebody really needs to do a thesis on this issue. I'd read it.
