I’m not a huge fan of it either but versatility and hybrid players has been the rage at every level of football for a long time. Every program has a bizarre name for a hybrid player in their defense whether it is striker, moneybacker, star, etc... The NY giants are hardly innovative and had a big nickel ( 3 safeties) package as their base defense in 2010.
At the end of the day guys with the size and athletic ability to play multiple positions are valuable because they can stay on the field and rotate positions.
My issue with the striker position is that it’s almost a dumping ground for players even though the position can be very demanding. Manny got pretty short with a reporter when a Frierson got lined up 1 on 1 with a Florida receiver (went for a huge gain and TD) and he was questioned about how that happens. If they want the striker to sometimes be a nickel corner, 3rd safety, or linebacker they need to recruit some freaks not dump slow footed safeties and corners there.
I think Washington eventually becomes a linebacker personally and a pretty good one. I don’t see how he is going to ever man up with a fast receiver going deep in college.
