I'd be surprised, only because he puts his name on everything else - why make this one anonymous? I assume that the Andrew Luck thing came from some tech donor type, but that's definitely a WAG.

He doesn't put his name on everything. Apparently he's contributed to over a hundred buildings and could have had his name on many of the if he wanted to. I heard that he didn't even want his name on the new dining hall, but someone convinced him (which may be why it's "Arillaga Family").
