Stupid thing for the coach to say, then back away from.
Singling out players in the press in any negative way is something that shouldn't be done off the cuff. For weight and conditioning, it should be pretty obviously bad for a coach to say anything at this point in the season other than "needs to get into mid-season form" and, like his protégé Bird would also argue, do the [right type of] work in the summer that improves basketball performance, not necessarily the kind that makes a player look pretty on instagram, a calendar or magazine.
a player can be winded and out of condition without being overweight. More lifting than running will do that easily.
