Bo's playsheet and UM coaches' headset audio recordings

Look right there under Goal Line, the second run column. It says 'CJK5H"

Those aren't plays. Those are coordinates to a buried treasure. On the back of the declaration of independence. 

To answer your second question about headset recordings, what happens on the headset stays on the headset. I doubt coaches would want any of that getting out. Those would be some heated conversations. ESPN actually has an article about it today.

Neat.

It looks like it was all hand printed - not the laser printed laminated trifolds we see today.

It looks for 3rd and shrt, that there were 6 passes and 10 runs (?)

Guessing RT - right? WT - Wide?

The two digit plays are runs the three digit plays are passes.  

The additional writing on the situational list includes the formation details. 

Interesting.  And it's especially facinating if you watched Michigan football closely during the Bo years cause I'm pretty sure he only had four plays he liked to call:

1. Off tackle (always the first play of the game and ALWAYS behind the left tackle)

2. QB option.  In his later years it wasnt really much of an option - it was simply a keeper with a trail RB but for Franklin & Leach it was definitely the "go to" play for the offense

3. Draw.  This became a Bo staple in his later years.  I think in the 86 Rose Bowl, for example, he called something like 37 draw plays to Jamie Morris

4. Deep post.  And for God's sake NEVER throw the ball to the RB - they are meant to have the ball handed to them, not thrown to them, in Bo's eyes.

There might've been a play or two more in his arsenal but those four were the staples.

This complexity is why Matthew McConnaughey had to run "The Veer" at Marshall...

I'm surprised that headset recordings were made back then.  But if they were made, I doubt many survived.  A reel to reel would have probably been used to make the recording and those tapes are both expensive and large.  They most likely would have been erased so the tape could be reused (many many times).

If Bo were our coach today - I am sure you would hear on the headset:  "Give the ball to Bench.  Bench, you are an animal run behind Ruiz and Bredeson blocks, but pulverize anyone in your way.  Just do it son!"

Anyone know where I can get some recordings of Brady Hoke's headset conversations?

I saw a picture of Harbaugh's from this weekend... written in blue sharpie, covering almost the entire thing was, "Ben Fucking Mason"... true story!

assuming this is classic stuff (and that's a safe assumption) the double digit plays are going to be runs.  the backs are numbered (1-2-3) and the holes are numbered, even to the right, odd to the left.  so to the right the holes would be 0-2-4-6-8; to the left, the odd counterparts. 

the triple digits are going to be pass plays and the third digit is telling you usually what direction to slide if you're the o-line.

the other stuff is fairly self explanatory.  X and Z are your wideouts, Y is your tight end.   and a typical pass pattern is a 'Z out' you see up there.  that's a wideout and a slot both doing post patterns and then the slot guy turns out to a corner. 

I think one key to understanding this would be the list of formation codes. Here are the ones I remember (for some reason; I didn't even play football)

For a lot of these plays, the two-digit #s refer to the formation. the first number is how many RBs, and the second is the # of TEs. Since there are five total non QB/non-OL positions, any "Remainder" would be the number of receivers. So:

00= 0 RB 0 TE (5 WR)

22= 2 RB 2 TE (1 WR)

For passing plays, the a three digit number tells you about the play design. The first number is usually the # of steps in the QB's drop, the second number has to do with the routes that the receivers will run, and the third number is the blocking scheme. Someone more knowledgeable could fill in the gaps.
