Physical conditioning isn’t the main factor in determining if Perich should/could play both ways.
Big difference between playing both ways in HS and College.
Even I played 100% of the snaps in HS!
College defenses are way more complex and you have to understand multiple packages to ensure you don’t have blown coverages. This is also true in HS just going from class A up to the highest level. He wasn’t in the Lake Conference with a college level defense.
That’s just the defensive side.
College offense is the same, blocking packages, audibles, changes at the line are all very dynamic.
Add in that all the players are very high level athletes and the mental game is magnified to create a separation.
Don’t expect a freshman to be able to master all aspects of college football 5 games into their freshman season.
He may be smart and sponge up information at a high rate, but playing a major role on defense and being situationally aware on special teams at the most important position for punt returns is already asking a lot.
He seems to be handling it at an elite level so far.
And he sure is fun to watch.
