The Chase Elloitt effect along with the instant success of William Byron coming through the ranks.
Tbh I blame Jeff Gordon's ascent to stardom and every manufacturer wanted their "Jeff Gordon". Remember Kenny Irwin Jr (May he rest in peace), Ford was expecting him to be the "next big thing" without a lot of seat time.
Yet, we call 17, 18, and 19 year olds flops or busts because they may not win for a season or two. Look at Corey Lajoie, I think in a couple of years barring his success with GoFas or FRM or any organization in the future, he will be a growing name in time to come. Remember how much of an issue he was when he was with BK Racing? Crashing, DNQing, etc.
