I would not trade Ott 1st. It could turn out to be jack hughes, what would be a franchise turning player. NO to OTT 1st.
Its not even just Hughes, this entire draft is tailor made for the Avs, its incredibly deep on Center and has good options on wing as well. Even without 1st OA any pick in the top 8 would almost certainly fill a massive need for the Avs. Even if Ott loses the lotto and goes to 4th a guy like Cozens would be a perfect fit for this team.
