Also kinda surprised we don't see the big defensive tackle they talked a lot about during fall as a young up and comer (Howard Brown). Especially that since his size and athleticism is kinda unique.
Thinking about this more - I wonder if they see Tyler Onyedim as the Enyi role. Howard Brown can be the 3rd DT/NG behind Lee/Singleton. If TO is mobile enough to fill the role that Enyi plays at 6'4" 290, that would be a huge boost to the entire DL. I know Ryan Harklau was praising what he saw from TO in practices.
