Dino,
I think it's a fair question to ask who you would pick fourth over taking Parker, unless you are just all talk which it's becoming abundantly clear that you are.
You don't think it's a fair question, you think it's a "gotcha" question. You want me to name a prospect so that you can then "get me" by contrasting a completely unproven and mostly unknown player with a player who has produced something in the NBA, because the latter player is always going to look better by default.
It's not an unfair question in a vacuum, but it's not really an
important question. I am a nobody on a message board. I am not on the staff of an NBA franchise. I don't know which player or players mocked in the lottery or mid 1st will be better than Parker. Most NBA front offices don't and won't, either. But based on basically every draft in history, I am fairly certain there will be such a player or players. Here are some recent years where a player more valuable than Parker or Big Dog was drafted, only between 4-15, excluding the top 3, not even counting any late 1st or 2nd round sleepers.
2013 Noel at 6, Antetokounmpo at 15
2012 Lillard at 6, Drummond at 9
2011 Kemba at 9, Klay at 11, Kawhi at 15
2010 Cousins at 5, Hayward at 9, George at 10
2009 Curry at 7, Derozan at 9
2008 Westbrook at 4, Love at 5, Lopez at 10
2007 Conley at 4, Noah at 9
2006 Roy at 6, Gay at 9...but since Roy got hurt and Gay isn't that valuable, I'll concede this year
2005 Paul at 4
2004 Deng at 7, Iguodala at 9
It would be unfair
in hindsight to rake a GM over the coals for taking a Parker or Big Dog over those kind of players. But any GM who would be satisfied
before the draft taking a Parker or Big Dog ahead of those kind of players is a bad, unambitious GM. You want a name? Just look at the 3rd through 15th slots on DX's mock draft and choose a couple names at random. That's how equipped we are as message board fans to accurately pre-judge these prospects compared to the information actual NBA execs and scouts have. But yeah, it's almost a guarantee that a better-than-Parker player or two exists in that range.
That's what the Celtics should be shooting for with the 4th pick. If they keep it. If they don't keep it, if they use it in a trade package, then they can
definitely get a better player.
p.s. As I will continue to do whenever "TheTruth" trolls me, I invite everyone to look at my signature.
