Don't sweat it. This is why Joe has no friends.

But I can attest to the fact that Joe was there, as he goes to all games. By himself, or course!
Still, I do have to make a confession. When I read the comment about Sam winning that game "single handedly," I kinda raised an eyebrow as well, because my memory of that game was quite different that yours, much to the extent that Joe already explained.
Sam certainly had some moments as a freshman, and he did play well in that ND game. But he also had many games as a freshman were he made little impact, which is very much why he didn't play more minutes. Having said this, Sam was clearly superior to Jamel as a freshman, which I suspect was the point you were trying to make.
However, Jamel was better than Sam as a soph, and much of this was because Sam was really struggling with the pain of tendonitis during the entire first half of the year. He was also playing mostly the three behind Mike Cook, who frankly was the better player at the time.
As the year went on, Sam's knees improved, and he really started to get more time, mostly at the four instead of the three. He played as Levon's backup, as well as at the four when Levon slid over to back up Aaron.
But when it comes to comparing Sam and Jamel as juniors, the edge still must go to Sam. Sam was a first team All-Big East player that year, and carried the team through many of the games after Cook and Levance went down.
But at the same points in their careers, I don't think Jamel is that far behind. He's already a much better passer than Sam. But he's not quite the explosive scorer that Sam was. And Sam was better off the dribble with his exaggerated ball fake.
Finally, Sam was a clear All-American as a senior, and obviously, Jamel is not there ... yet.
To end, I just wanted to acknowledge your fine line: "he is McCartney to Young's Lennon."
