No he can't you don't know poo about the human body. He will lose explosiveness and have leg problems if he add much more then 15 more pounds to that frame.
He has the same body type as Durrant, Brandon Wright, Tyson Chandler. Not much weight can be added to his frame without problems. This isn't create a player feature on 2K. You can't have a Skinny player weight 245 to 250 pounds. This is simple human anatomy.
1. Best Defensive Bigmen
Marc Gasol -7'1 265
Tyson Chandler - 7'1 240
Serge Ibaka -6'10 235
Jokaim Noah 6'11 232
Tim Duncan - 6'11 255
Dwight Howard - 6'11 265
Larry Sander - 6'11-235
Roy Hibbert - 7'2 - 280
Noel - 6'10 215
2. Grizzles lost because they are young but they were still in the final four.
3. Indy lost for the same reason but again having a post up scorer made them better then all but 1 team in the east.
4. The Spurs don't win without Duncan and Splitter stop Z-BO and rebounding and get easy points in the post. No team can win just jump shooting from the wings.
Last we already have a kid developing into a defensive force we need to add a Post scorer to go with him. Noel is 3-4 years before having a serviceable offensive game and he will never be a back to the basket player. Plain and simple.
You used Durant as an example of his body type.
Durant in College weighed in at 215, he now weighs in at 235. He's added 20 pounds and is just as explosive, if not more so. He's a better finisher at the rim because of it too.
Wright was already filled out when he was in college and had maxed his frame. The same is not the case for Noel.
Also Noel weighs 206, not 215. He has plenty of room to grow. He can get to 220-230 easily and still be the quickest PF/C in the NBA. He's got freakish speed, quickness and reaction/timing ability. <- That's why he's the #1 ranked prospect. It's not about weight though, it's about strength and skill set. The NBA is getting smaller weight wise and more finesse in nature.
As for Noel being a finisher and back to the basket guy, he already has the ability to finish with both hands at the basket and with a mini jump hook. He just lacks consistency. That comes with age and repetition. He's 18, he's going to be 27 after his first contract and RFA contract are up. I'll admit he would be a big risk though because of his age, developmental time and the injury concern. however every single player in this draft has super major question marks. He's just got the fewest of the bunch.
The Grizzles lost because they couldn't get into the post effectively and had no Wing players to take the pressure off of the inside game. Same for the Pacers, The games the Pacer's won they had someone step up outside and make shots to keep the heat from crashing in around West and Hibbert. I never said the Spurs relied on just jump shots, I said they relied on wing and guard players for their scoring punch and that's true.
Of course the Bobcats are developing a defensive stopper, he's still really young and still just like a new draft pick each year. He's only 20, still younger then most of the kids that are in the draft. Same goes with MKG, just 20 years old.
They have a few years before they reach potential, 2-3 years to be exact. Why not take a player just as young that can develop along with them? If it doesn't work out, then no harm really. The Bobcats won't know anything about MKG or Bismack for another 2-3 years, add one more to that mix. Make it a defensive juggernaut, add the scoring in 2014 via Randle, Parker or Wiggins. Add in a FA or Two to fill out the Roster and you've got a team full of defensive stoppers, go all out guys with a potential all star PG in Kemba, and a superstar type player in Randle/Wiggins/Parker. Add in some scoring via FA and you've got a team you can keep together for 7-8 years that formidable in the paint both scoring and defensively.
