bibby doesn't penetrate to colapse any surrounding defense. he hangs too much outside. he might work for awhile with iso melo but, if you need a different look. he's useless.
so, i'll take baron and lin, anyday. baron only had 2 TO yesterday and 1 pf. it's not so much about his injury but, his bball conditioning/shape. i bet once he get his cardio to 90/100%, he's going to be a different player(also dropping some of that weight can reduce chances of joint injury. over the summer , not playoff times would be more a logical time to do it).
gamewise, he just got to stop penetrating too deep and passing it. just look for his shot instead.
