Intramural 7v7 flag football , need help creating a good offense/defense for my team - Instant Rush

Hi! This is my first time here so idk if this is the right place but I need help with creating an offense and defense for my flag football team. I will most likely be the QB, as I play it when we are messing around, but I have no experience playing the position in a competitive settings. I played baseball in HS, so I can throw on the run, but don't know how much it translate. School just started and the team wants to start practicing in the next few weeks. It's a 7v7 league with an instant rush, screening is allowed but no real blocking. From what I gathered by asking around most teams rush 2 on defense, and have a center and 2 "linemen" on offense with 3 WRs. I was wondering the best way to tailor the team.

Me - Former HS baseball player, on the shorter side and not great top end speed, but good acceleration and lateral quickness.

Player A - Former HS WR, really fast, has great acceleration, and can run routes really well

Player B - Former HS basketball player, tall, athletic, and extremely long arms. Has ok hands, but not a great feel for the game

Player C - Former HS soccer player, strong and fast. Takes really great angles on defense but cant really catch and isn't super coordinated

Player D - Former HS track star. On the shorter side, but extremely fast and athletic.

Player E - No sports background. Medium height and build, struggles to catch the ball, slowish, but makes good cuts

Player F - Former HS baseball player, athletic enough with medium height but a little on the bigger side.

Player G - No sports background. Isnt super coordinated but really great acceleration and long arms

Player H - Played football in HS at a rly rly small school. Not the fastest but super shifty with good hands and medium build
