It never stops amazing me, that some of the trees we tried to save survived!
Work some real good soil around the roots, don稚 bunch them together and keep it watered along with good tie downs so the roots don稚 get pulled around with every gust of wind.
Our most favorite tree for shade on the back patio was removed once and replanted with less than I see in your pic and then moved again about a year later and has flourished beyond belief .in the last 30 years.
