I remember reading that Red Auerbach used to play tennis everyday. When I read that Boston was still one of the teams wisely pursuing John Collins, but also now his teammate Bogdan Bogdanovic, I was like sweet I've long wanted Bogdan in Boston as well. But when I googled Collins and Bogdan the above pic was the first one that came up, so now I'm left with as many questions as answers. Is this some cyclical Celtics tennis thing? Is the cost of John Collins too high that Boston is going for a less expensive trade? But would these tennis players necessary be more or less obtainable for the Celtics?
