Olivet Nazarene (NAIA – IL) passing game coordinator / quarterbacks coach Calvin Renfroe joined us today to take on the 10-Minute Clinic Challenge.

In this quick clinic, coach Renfroe takes us through their process for reading a defenses alignment pre-snap. It’s a process that they drill every, single play and not just on passes, and he points out why.

Their S4 process, as he refers to it as, is also one that can be adapted to fit a variety of offensive schemes.

The 10-minute Clinic format is a unique opportunity for coaches to take viewers through one effective play, scheme, or technique that they can really dig into the finer points of and share in a maximum of ten minutes.

Do it, and get the “W,” but go over the allotted time, and you’ve got to take the “L.” The time starts after a very brief intro.

Head here to see all of the FootballScoop Online Clinic content to date, and fill out this form to be considered for a future full-length, or 10-minute clinic presentation.
