In Parker's peak he was arguably a top 3-5 PG but he's no longer as quick and got himself into way too much god damn drama which probably doesn't help. The league is also loaded with young PG's on the rise so its an even more compe ive position than ever before.
Of the Big 3, Parker offers the fewest intangibles, defensive plays, versatility, etc. Bruce Bowen and at times even veteran backup PG's made up for some of Parker's/Spurs weaknesses in the past.
Parker's court-vision/passing/handles/decision-making really isn't very good either. At least when it comes to managing a good assist to turnover ratio especially against the Grizz in the playoffs. He has also failed to utilize Richard Jefferson's few strengths like feeding him on the fast break but thats also because Parker is a score first player and RJ was just a bad fit.
Parker's midrange shot seemed like it kind of disappeared in the past year or two or at least it seemed more inconsistent.
I like that Parker got better in the reg season but for the healthiest and youngest member of the Big 3 he just doesn't have the impact that you'd expect. I don't like Parker mostly because he's been disappointing in the past two playoffs and because he's been getting himself into really stupid stuff like sexting. I think Parker getting involved with ex-Spurs wives is just a bad, bad deal for not only Parker but the locker room as well.
