My old professor told me to ignore the 'ritual pit' theory at the Sutton Hoo site

Honestly, back in my undergrad days around 2010, my archaeology professor was adamant that the famous ship burial at Sutton Hoo was a one-off king's grave, and any talk of it being part of a larger ritual landscape was just trendy nonsense. He said focusing on the single ship was the only 'real' work. But the new geophysical surveys over the last five years have shown a whole bunch of other mounds and structures around it. Tbh, sticking only to his view would have made me miss how the site actually functioned. Has anyone else had a mentor's strong opinion proven totally wrong by newer tech?
