All of it, man. Parker played the least amount of minutes, scored the least amount of points and took the least amount of shots per game since his rookie season. He is old, limited and not that good anymore but the team losing in the playoffs isn't an indictment of him.
The blame mostly falls on the shoulders of Popovich, Leonard and Aldridge. Parker, Ginobili and (last season) Duncan are too old to make a significant impact, but y'all are either too stupid or too afraid to place appropriate blame.
Same reason y''all run to head Stephen Jackson for quotes or cry about an old ass PG being " ty, TOSB or POS."
Which is hilarious in actual real world context because Parker is infinitely more succesul than all of us. "
"But, but, but he did got old is ty now and played poor a bunch of times in a long storied career."
