What should be the first thing (not that we're looking for things to criticize), then?
Biggest worry of mine is whether he'll accept his height deficiency and find ways to work around it, instead of just accepting and and deciding to remain as a potent 6th man or a serviceable starter for the rest of his career. My first concern for Millsap is whether he has the mentality to raise his "ceiling" that people have seemed to put on him throughout his career, something he continuously does. To me this is his hardest challenge yet, however if theres anyone in the NBA who has proven fans/critics wrong SEVERAL times over it is Paul Millsap. I am not worried for his physical gifts, reach height etc. I am most worried about how he approaches improvement mentally, whether he decides to just give up or whether he'll keep trying to improve.
To Millsap's credit, he has improved almost every part of his NBA game--rebounding (still had to develop it although he was a top rebounder in college), shooting, defense, stamina. But you can't teach height, and you can't develop height much, either. So his height is where his ceiling (pardon the pun) lies. He has had his times where he has flustered Kevin Garnett, but he'd have to be near flawless in every other part of his game to hold his own against a Gasol (either brother) or a Bosh or maybe even an aging Duncan. Boozer couldn't--not against Pau and Duncan, at least--and Jefferson or maybe Kanter might be able to, if the former wakes up one day and decides to play defense.
This is where I vehemently disagree, as a player SHORTER than Paul Millsap DENNIS RODMAN could defend people much taller than him. This is the precise reason i introduced him into the argument, I I cannot understand how you continuously shoo off the fact that there have been defensive Aces at PF that were much shorter than Paul Millsap. Defense isn't about whos taller, whos stronger, etc. If you had any sort of Basketball knowledge coupled with critical thinking skills you would realize this.
Your comparison is apples to oranges--or at least golden delicious apples to Johnathans. On a Jordan-manned team, Rodman was not a cornerstone; he was a garbage man offensively. Meanwhile, the Jazz need more from the PF position than somebody who merely cleans up the boards for putbacks. That's why Millsap vs. Rodman is a tenuous comparison as long as the Jazz need more from the PF spot (including Millsap).
Not once did I wish for Millsap to be like Dennis Rodman like player, nor did I state the Jazzes need for a player like him at all. For the 80th time the only reason I brought Rodman up is to prove that short players can defend in the NBA, something people use as Millsaps number one weakness.
While Barkley's current midsection is far from fading, a comparison of Millsap to the Barkley of the 90's is a fading comparison because the NBA players are more athletic these days. (I don't know if average height has gone up or down, but Millsap represents approximately the average height for all of the NBA.)

Never said its an easy comparison, but you are either trying extremely hard to win a pointless internet debate or youre just blind, if you seriously think that Paul Millsap either as just as good as Charles Barkley, or would have Barkley-esque career in the Nineties.
Did I say that Millsap's shortcoming was primarily on defense? Against taller bigs, his height hurts him offensively also. You're the one focusing on defense. But anyone who has defense as his shortcoming has a rather large shortcoming. Even Big Al's key shortcoming is not defense as a whole.
So lets see: he had one of the top FG% among PFs in the league, one of the highest true shooting percentages in the league among PFFs, and averaged 17 ppg in his first starting season of his career. His offense is absolutely anything but alarming, or a shortcoming as of this point, and he matched up regularly against much taller players throughout his 70+ game season. His defense is easily his largest weakness, however the point I'm making is that he isnt physically limited to being a poor defender for the rest of his life, and it is up to his work ethic to probably become quite the solid defender for the rest of his career, given that one of the best defending/rebounding PFs of alltime was a lot shorter than him.
