Lakers: You have a solid starting lineup, but most of the players have some kind of deficiency or flaw in their games (LMAM shooting, Dirk+Calderon defense). Who would you say is your most important reserve, and how will you integrate them with starting players to counter teams that can exploit weaknesses at key positions?
I have already addressed the perceived flaws of LRMAM, Dirk, and Calderon, so I'll go ahead and answer your second question.
There really is no particular "sixth man" on this team simply because of how versatile the bench is. Delfino/QP solid 3&D guys who can play both SG and SF. Barea is a great change-of-pace guard off the bench, but like I mentioned earlier, he is a great PG fill-in if Calderon gets hurt. Davis can play both PF/C which allows O'Neal to stay rested for the postseason, although O'Neal seemingly found the fountain of youth last year by playing a solid 18.7 minutes off the bench for Phoenix. If you go really deep on our bench, you'll find three youngsters (MCW, Lamb, Olynyk) who all figure to have prominent roles for their teams this upcoming year, but we have the luxury to keep them as third-stringers who will see garbage minutes in blowout games.
