This may get into a semantics based argument, but let's assume that Veleno's career falls routinely between 40-50 points. And in theory, there are 62 top 6 centers in the sport. Just exporting data from Hockey-Reference, sorting by point totals, and removing all players not listed as a center, I have the cut off being 47 points in 2018-19. Now this is not at all representative of reality because of the inaccuracy of players listed as center.
For example, this list considers: Huberdeau, Guentzel, Hoffman, Reinhart, Tatar, Dzingel, Oshie, Forsberg, Kreider, Konecny, Athanasiou as centers, which we know they realistically spend a majority of their time lined up on the wing. Regardless, let's add 10 names to the list to account for the "positional indifference" of the data set. That brings us down to...the Alex Kerfoot/Cody Eakin type which is the 41/42 point threshold.
Considering the projection of Veleno as a plus defensive center, who wins draws, skates well, and gains the offensive zone well, there is no reason to think he isn't in the discussion of a second line center. We also can consider how much deployment can influence production. An example being: Justin Abdelkader Circa 2014-2016. Put Abby near the top playing 18 minutes a night with Datsyuk consistently creating points for him, looks like a serviceable second line level player. Remove the straw that stirs the drink, you get a shell of a player. If you are electing to put Veleno down the lineup to play with someone like Adam Erne and Evgeny Svechnikov, you will create the 30 point defensive center you are suggesting him to be. Put him on the second line with Filip Zadina or Anthony Mantha or Alexis Lafreniere, you are likely creating the two way center who will be on the higher end of the point spectrum.
The state of the team is going to go a long way in determining what Veleno is going to be; if the Wings come out of the draft with QB, you have to believe that Veleno is positioned to be among the best 3rd line centers at his peak, and if Veleno is worked into the lineup next year early and plays 2nd line center out of necessity, he may show enough that the team is comfortable building with him in mind.
For reference, here's an old article from 2011 discussing production by position and line.
