ESPN projects Steelers roster

What are the latest rumors with the Steelers 53-man roster? One preseason game remains and cut-down day is 6 days away. Are the Steelers going to keep 4 QBs? Is that sensible roster allocation? There was a roster projection put out by ESPN today that kept 4 QBs. Some notables left on the cutting room floor were Robert Spears-Jennings, Esezi Otomewo and Kaleb Johnson. There is growing sentiment that Kaden Wetjen is on the bubble. Are 5 DLs enough? Will Will Howard have a better career than Kenny Pickett?
