MAM, I wouldn't worry. A LHP with college experience is like gold to most summer league organizations, particularly one who had an invite to Northwoods or the Cape. If he is flexible, he will have ample opportunities, provided summer league ball even happens. That is the bigger question. That and the whole host family issue (with Covid-19 concerns).
Yes, there is likely to be a dropdown scenario for the few top leagues but he still holds a pretty nice chip. Worst case, he waits until the season is about half way over when guys start hitting innings limits, achy arms, poor performance, etc.
If you are looking for immediate direction here, you may want to include some of his college numbers.
