lonelytoaster brings up a good point on sweetney's weight. it is hard and hazardous to assume you know the motivation of anyone. guessing is about all anyone can do.
so in that vein, another way to look at sweetney's weight is not that he came into camp simply overweight and out of shape nor that he does not care.
maybe he does care and right now, is weight is down from 1 year ago. that is, maybe ainge saw someone who is willing to lose weight and has demonstrated it by working hard to become "relatively" slim.
ha, ha. i doubt this is the case, but who knows? he may weighs 300 now, but 1 year ago maybe he weighed 400. if so, then maybe ainge thought there is hope.
