Here's what I'd like to see with these freshmen OL since we already have considerable size and stature there.
Before and/or after every practice session have one or two experienced mentors from each line group (ie. tackles, guards and centers or maybe guards and centers together), say Halter and Sharpe for the tackles and Thurman and Dillard for the centers and guards, get their freshman position groups together for playbook and film study. No coaches, just the players. Maybe the whole line together in some sessions.These are cram sessions so the freshmen have it in their heads during and after practice. Get the playbook and the line calls down like you would in an AP Chemistry course in high school.
Then as fall practice develops have them spend some time every practice going against the 1st string d-line. Start slow with some straight up run blocking then move to some simple 3 step drop pass protections, then some simple blitz schemes and then some 5 and 7 step drop pocket patterns and finish off the preseason with some more complicated blitzes and line stunts. Bring them along with intensity, have them create some chemistry of their own like the season is dependent on it. Along the way have them drop in to the 1st and 2nd string lines for quality reps alongside some (admittedly limited) experience. Playbook and line call proficiency and unit chemistry developed in a single fall camp. I think that's how I would approach it under the given circumstances. A methodology of necessity.
Comments welcome.
