I have had 2 guys with the exact same ratings except for stamina, which is very different. I played them on the nearly exact same settings at the 5 in the same system. Both played on Slowdown teams SO year and normal teams JR year. Both were on teams their SO years that were the most talented in the country, surrounded by other strong options/high PA. Then, their juniors years they had to deal with freshmen starting around them and a slightly increased distro. Let's compare their SO and JR years.

Although Ropp has slightly better SP through both years (5 points SO year and 2 JR year) as well as better LP (even SO year and 4 points JR year) and higher ATH (3 points SO year) this is mitigated by Adames' PER advantage (10 points SO year and 11 points JR year). We are left over with a letter grade FT advantage for Adames. Adames was a better scorer than Ropp (excluded stamina) during this time period by a very slight margin.

The main difference is better stamina for Ropp (7 points SO year and 13 points JR year) as well as a harder schedule (6 SOS average for Ropp in his two years 12.5 SOS average for Adames).

Most of the community would expect Adames to score slightly more per minute with a slightly higher efficiency than Ropp from the FT/PER/SOS advantage easily outweighing the SP/ATH advantage.

Adames:
MPG: 24.7
PPM: .471
EFG%: 1.08

Ropp:
MPG: 26.3
PPM: .495
EFG%: 1.16

Ropp cannot only play slightly more, but was also actually MUCH more efficient at a slightly higher volume.

Why is this? Scroll through my play by plays this year with Illinois, and you will see 1 constant sight: Matthew Adames in the game at fairly fresh. After the first few minutes of the game, the system just cannot sub him in and out fast enough. He not only plays fewer minutes than Ropp much is much more tired while he's in the game, resulting in a much worse player.

Be wary of low stamina, even in a Mo/Man on normal.
