It's safe to say that zero is back in vogue in the NBA. Some notable fellow No. 0s are Love's college teammate Russell Westbrook, Damian Lillard and Andre Drummond. I personally choose to give Gilbert Arenas the credit for starting this trend.
If you were wondering -- and of course you were -- the three previous Cavs to have worn No. 0 are Lari Ketner, who played 16 games in Cleveland in 2000, Jeff McInnis and C.J. Miles, per Basketball-Reference.
So, if you wanted to, you could say that Kevin Love was the next Lari Ketner.
