Harry is exactly as advertised coming out of college.
Both strengths and weaknesses:
2019 NFL Draft Scouting Report: N'Keal Harry
He's not an explosive burner and won't get much separation. His game is contested catches (and red zone?) - Anquan Bolden-type. As advertised. Good blocker, good at overpowering a corner for the ball.
It was no secret in the draft. The question then is: if Brady wouldn't throw to guys like that, preferring the Edelman twitch-open style, and if McDaniels won't scheme/Belichick won't accept the jump-ball style, why the f*** did they draft him with AJ Brown (my favorite) and Deebo Samuel (my other favorite) sitting on the board?
I have a hard time blaming Harry, given Brady last year and especially Newton this year, but if a team isn't going to match its picks to its desired style...well, isn't that exactly how BB keeps finding people like Vrabel and Van Noy? Square peg/round hole and all that.
Harry would, and likely will, have a good career - somewhere else. Watching the Seattle game, the TD catch last week, and the fighting last night tells me that he's an NFL receiver.
It's like with Metcalf. Perfect system with him in Seattle as Wilson throws those sky-balls. Get Harry in the right system for him, and with a QB and OC who want to get him the ball, and he'll perform.
