He still looks like the same Monta but the entire team has been a terrible fit for him since the trade. Just the pace that they play along with how a Jennings/Monta backcourt complements each other far worse than Curry/Monta.
Monta also doesnt seem interested being there longterm. I read that he has been staying in a hotel since the start of the season instead of renting a house or mansion and hasn't brought his wife & son up to Milwaukee to see him play. Apparently he & his wife live in Memphis.
