Can I play football as a freshman with little football knowledge and experience?

Hello! I am an incoming freshman (6'2, 160 lbs) wanting to play football and I really have no experience or knowledge of the game. I joined my 8th grade team VERY late into the season (3 weeks and 2 games remaining) and played defensive end but that really wasn't enough time to pickup a good understanding of the sport and i had very limited playing time. I also don't really know anyone going to be on the team. Is there anything I should know/ do before starting summer workouts or is playing highschool football with no experience going to be too difficult?
