Just one day. I sign and sign. But I don't want to sign all day long. The basic autograph request has become more soulless and life-sucking than Tuna Helper. Scumbag collectible dealers hire kids to get signatures and then sell them.
Parents push their kid forward to get the autographs of people the kid has never heard of.
One time, former ABA and NBA star Dan Issel came out of practice in a hurry and signed as many autographs as he could until he finally had to stop. His wife had gone into labor. I understand the salary cap. I fathom the physics of the screwball. But I don't get the autograph.
