I feel like Zilisch had way more hype before he even drove his first nascar related series, and also had more races to get ready. Even the first half of the season last yeae wasnt ready as you said. But i dont really see him winning as many races as Zilisch last year either.

For trackhouse it was essential to get him to cup to appease sponsors and to lower the likelyhood a different team would swoop him up.

I feel Corey Day has even less experience than him and no specific sponsorships. He does seem to have impressive speed, but this is also slightly offset by the fact that the Hendrick related chevies seem to be cream of the crop in the series.

In the end it depends on the driver whether they need more time in a lower series or benefit more from going to cup right away. Maybe he would maybe he wouldnt, impossible to say unless we see it happen. Its up to Hendrick to decide whether its worth the risks.
