I do, since it's his first MLB card... And because I have it
I have very loose definitions on rookies. These are dictated by card size/type, regional vs national distribution, availability, and by overall aesthetic of a card (meaning I'd never kill myself to get what I thought an ugly card). In short, my definition is very subjective and very personal and allows my Leaf Jackie Robinson and my 1948 Bowman Musial to be "rookies" in my collection. I wouldn't feel need to argue my definition with anyone else's, as in my mind it's largely a "to each his own" thing.
And and BTW- if and when I ever land an N172 Nichols or a Bond Bread Robinson, I'll probably consider them rookies.
