I don't know if you're serious or not. But fine. I'll use this example instead.
Kevin Durant: 6'9, 230 lbs.
Paul Pierce: 6'7, 235 lbs.
Same size according to your logic, right?
Or...
Chauncey Billups: 6'3, 202 lbs.
Jamal Crawford: 6'5, 200 lbs.
Same sized players, right?
At the time of the 2003 NBA Draft, Dwyane Wade was essentially the same size he is now. For evidence, please click the following links to see his measurements at the time of the 2003 combine:

I'm not sure where you are coming up with the notion that Wade had only bulked up since the Heat's le season. It's simply not true. However, I'd be more than happy to allow you to provide some evidence to that contention. Wade has added maybe 5 or so lbs., but it has not been a noticeable increase in muscle mass or bulk. And he was already a thick and muscular physical specimen before his championship season, even before he entered the NBA.
The kid was a tank in college before he played in the NBA. He did not have the slender build Manu has. Where is your evidence to that claim?
