Middle Onside Rules
L1/R1- Both of these players are to take out the center. A big coaching point here is they do not look for the ball at any time, they strictly aim to decleat the center. This is very important, because the center is the only player the return team can really utilize to destroy the middle onside. Each player should aim at the near shoulder of the center, and be ready for one heck of a collision (see video below)
L3/R3- These do the exact same thing as L2/R2, however they have to take more sever angles to cut off their defenders. Again, the key is the inside shoulder of the tackle, and do not look for the football.
