DoDo on the rise: Who's better than RoCo?

[SleepingHero]

An interesting question I think should be posed,

If DFS is performing so well in our system, how much better would a guy like RoCo be, given that he has a much better knack to score than Dodo? 

Only reason why I say that is because RoCo has 6 seasons of 36%+ from 3pt percentage, a sample size of 326 games. While this is DoDo's first year (so far) ever getting higher than 31% from 3. And unfortunately DoDo has shown in the past that he starts hot and by January his 3pt shooting dies. Last year Dodo was averaging 39.8% from 3, and then by 12-14-2018, his 3pt shooting took a nosedive. From 12/14 on, he shot 26% on 3 attempts a game. It is undeniable that Robert Covington is a more consistent 3pt shooter. 

So wouldn't RoCo fit in even better than DFS? The analytics show that they are remarkably similar on the defensive end, so they aren't giving up anything there. Plus the Mavs as a team take the most open 3's more than anyone in the league, and Dorian receives a lot of these looks. Given that RoCo is a better shooter, wouldn't he be that much better than Dorian?

Again I'm in the camp of DFS AND RoCo, not either/or.
