I think the jump from Jr. Middle (guys that start off there) to Super Middle and a decent Light-Heavy is easier than guys coming from Jr. Welter and Welter going all the way to Middle.

When you compare the average height and size of guys at Jr. Middle to Super Middle, there really isn't a big difference UNLESS the Jr. Middle is a guy who came from Jr. Welter and/or the Super Middle is a guy that came from Cruiser or Light-Heavy (very rare...).

Even when Chad Dawson came down to fight Ward, as weight drained as he was and looked, you can tell he was BIGGER than Ward.
