But in a sports environment where every piece of evidence is a potential advantage, these things matter and players' stock can and should rise and fall based partly on this information.
I wasn't in the gym watching jumpers and listening in on interviews, so the only real objective information I have access to is the measurables. A lot of guys improved their stock, some guys disappointed, and many prospects stayed right where they were after opting not to participate.
Among the perimeter players, many of the top prospects helped themselves.
-Shane Larkin has gotten mixed reviews based off of his combine performance, based on his disappointing
-Like Larkin, Zeller impressed despite his less than ideal size. His wingspan is the same as his height, which is normal for a human being but lackluster for a basketball player, and his standing reach is not impressive, But his athleticism is elite. His sprint speed and land quickness both compared to the guards at the combine and his standing leap was the best at the combine
-Otto Porter, who was considered the top SF prospect after the NCAA basketball season, remains in that spot. One of the main concerns about Porter as a prospect was that he's a good athlete but not a great athlete, that he has good size but not great size. All of this was confirmed, so his overall solid showing will keep him in that top 3-5 area for the time being.
-Victor Oladipo, on the other hand, still impressed people with his athleticism, but his physical size may pigeon hole him at the shooting guard spot. He is 6'4.25" in shoes but his 42 inch maximum vertical was tied for second best at the combine.
-The two point guards that faced off in this year's championship game, Peyton Siva and Trey Burke, have totally different games but were both considered to be on the shorter side coming into the combine. However, both measured slightly bigger than people expected. Siva measured 6'1" in shoes and Burke came in at 6'1.5". They're still going to have a hard time guarding the bigger PGs in the league, but at least now it is not a glaring problem.
