4. Gregory Rousseau in 2021
Gregory Rousseau had a lot of hype coming out of college. Despite playing for some bad University of Miami teams, a lot of the talking heads looked at him as the next great defensive lineman. Through two years in the league, he is one of those guys who has sneaky good numbers that you may not realize unless you are locked in to Buffalo Bills games.
He missed four games last year, but was still able to put together a season with 27 solo tackles, 10 tackles for loss, 14 QB hits and eight sacks. In only 13 games played, that's pretty impressive for a second year guy. Imagine him on the defensive line with Leonard Williams and Dexter Lawrence. Just awesome.
The butterfly effect is real with this one. The Giants initially took Kadarius Toney with the 20th pick. Toney never produced for Big Blue on the field, but his worth as an asset proved to be huge. He was traded to the Chiefs in 2022 and ended up winning the Super Bowl (good for him).
But, what the Giants got back from the Chiefs was flipped this offseason in a trade package that brought the G-Men Darren Waller. So, technically, if the Giants never drafted Toney, Waller may not be a Giant.
