Yes. Caleb Wood and Eric Osmundson were transfers who contributed meaningfully but weren't stars. Mosh would be one of those too.
I'm not sure if there will be as many star transfers in the era of NIL and the transfer portal. The likely stars will have many options. We will need to find those players who really just care about the Ivies over other high quality options, lower quality options, and NIL I'm not sure the era of free agency will appeal generally to Ivy administrators, as the Ivies broadly don't need one year rentals even if the athletic teams do.
