very few teams do a complete 180 in one offseason. lively has already proven he makes a huge impact on our team defense but we cant expect him to resolve everything. dallas has a very strong core with luka, irving, grant, and lively. they just need to refine some of the supporting cast.
Green is a really good defender against guards but bigger players he struggles against.
grant is a little too slow and does not have enough length to go up against quicker players. dallas really just needs a solid, big, athletic wing defender (hopefully omax can develop) and a legit bruiser type back up center (someone like biyombo but hopefully younger and taller).
I really like OMax. If he doesn’t earn time on the court this year that will be a real bummer, and there are worrisome trends about rookies who never break the rotation in their first year. Hope to see him soon because you’re right that he fits the exact profile of the type of guy I think we need to add.
