Vesalainen was top end at the u-18, and in some ways better than Tolvanen at the u-20, in my eyes. He played more of a pro style game in the u-20.
We definitely mean other tournaments as on those three pre-draft U-18, U-20 and U-17 tournaments where both Vesalainen and Tolvanen played, I don't think anybody would have chosen Vesalainen instead of Tolvanen.
Just for fun, combined stats for those:
18. 18+7=25, +5
vs.
18. 7+9=16, -3
There was also an additional pre-draft U18 tournament, but as Tolvanen was already a star at that level, he didn't attend that, but Vesalainen did. I guess you mean that by him being top end at the u-18?
On those pre-draft U18 & U20 they both attended, it was really night and day for the smaller guy.
