Yes, he's "that" Danny Ainge.
Before he was a Celtics superstar, he was a failed Toronto Blue Jays prospect.
This card came from the very first Topps Traded Set in 1981. I didn't follow the NBA at all, so when Ainge left Toronto for the Celtics, it meant nothing to me. But if you think about it, aside from Ron Reed and Ryan Minor, it's hard to think of too many other dual sports stars who played both baseball and basketball.
Imagine though, going from an expansion team like the Blue Jays to playing with Larry Bird, Robert Parrish and company. Talk about going from the outhouse to the penthouse quickly!
