http://www.thehuddlereport.com/archi...vid.Njoku.htm: "When he is on the line of scrimmage in a three point stance he looks like a frog sitting on a lily pad. His blocking boarders on the worst I have ever seen to… pitiful. His three point stance alone shows a lack of interest and defiance to coaches and his route running against man to man boarders on the worst to pitiful also. He does good against zone coverage’s but truthfully at this point of his career I don’t see him developing into a tight end, maybe a slot receiver and third down red zone receiver but a true tight end…not going to happen."
https://www.si.com/nfl/2017/03/24/da...outing-report: "He tried hard as a blocker, which is the nice way of saying that he’s not a very good blocker. Njoku is more of an in-the-way presence than anyone Miami could trust to make real headway. Not that tight ends should be left alone with edge rushers that much anyway, but the Hurricanes usually had to make sure they had help for Njoku in those situations. He could create an initial stalemate as a run blocker, but that was about all—any counter move or extra push from the man he was blocking made things difficult for Njoku."
https://www.profootballfocus.com/dra...-te-miami-fl/: "Struggles when tasked with sealing 8/9-tech’s to the outside on front side of gap-scheme runs; often gets beat to the inside forcing RB to bounce the run to the outside. Can get too tall when moving laterally blocking inline, allows defenders to get under his pads and control the movement."
I don't know which set of reports is more accurate, but I get a sense that Roku box is just one of those athletic specimens that scouts fall in love with. He is green as grass, raw as hamburger, and has no idea how to actually block someone. When did that become a 1st round pick? Look, I'm certain that if the Steelers were to draft him he would be a dynamic weapon in Haley's system and I would likely love him as a player. But in the strict sense of looking at him versus other potential first round selections for the Steelers, I can't say I would root for them to draft Ninjagaiden over TJ Watt.
