Yeah. Both players are important -- I refused to vote.
However, its hard to argue that Smart doesn't have an impact. Not only does he raise the energy level of the team when he is in the game (something that is simply not quantifiable by fans, but probably is with the player tracking cameras and teams), but he has single-handedly swung several games, including playoff games.
Those plays against Harden were great, but what about switching on to Milsap in the playoffs? What about his offensive outburst against the Cavs? There are other examples.
I like both players. I'm glad we, as Celtic fans, get to debate silly thoughts like this, while arguably we have 4 (maybe 5 depending on what you think of Rozier) other better scorers on the team.
