Former Full Time Fan Has Questions

[fifteenth]

Hi Mavs peeps! I haven't had time to be a full-time follower for a couple of years now. Can y'all help a brotha out and catch me up? I have questions. 

1. Is Luka pretty much locked in to being an overweight NBA player who will never reach his potential because his lack of being in shape will cap his ceiling and cut his career short? A couple of years ago I had hope that he'd figure the eating part out as he matured. Now, I'm beginning to think "it is what it is" on that front. What say you? 

2. Is Kyrie here til traded? Or is he here for fat Luka health insurance? And will they be able to actually play well together this season? 

3. If the team is bad this year will we get a new coach? 

Thanks, pals!

Looking for the season predictions thread and found this set of awful takes! Bring me my crow plate, I'll chow down.
