The Pats run a variation of the Erhardt-Perkins offense. I'm not too familiar with the play calling, but I think you're going to be disappointed. The offenses with long playcalls are west coast offenses. Those are the ones that are like 11 Green Right Sluggo Fly Curl Double Tango 67. The West Coast flat out says the route in the play. I'm not sure exactly which WR gets what, but there's a method to it. The Erhardt-Perkins o relies on numbers instead of words.
Here is the most comprehensive bit I found...
The system uses all kinds of numbers.
Play calls work like this:
0, 1, 2, 3, 6, 7, 8, 9 are base formations -- on even numbers Y is on the right, odd numbers on the left. The numbers denote backfield sets with modifiers;
0/1 - I-Formation
2/3 - Far
6/7 - Split Backs
8/9 - Near
50-90 dropback passes
400 passes from other positions
H 40 = draw
1 On 58 hook = dropback
Ride 131 Utah = play-action
1 Out Slot 50 D-Slant Ole
Y is on the right, out represents the position of F, and slot denotes that the FL and SE are on the same side.
50 is the protection: 7 man slide with no hots.
I find most of the play-calls to be packaged in 2/3 man concepts.
The protection is the most difficult thing for me to grasp, and unlike WCO or Coryell systems, the protection digits vary from team to team. Gailey/Palmer protections are different than Weis, Mularkey, McDaniels, O'Brien etc.
These are the protections and rules from the Pats:
50-51 [7 Man Slide] No Hots, No Sight Adjusts, HB = Mike to Force Strong or Weak
52-53 2 back [6 Man Slide] 2 Strong = Y Hook, HB = Sight Adjust (Flare, Diagonal)
54-55 3x1 [6 Man Slide] 2 Strong = Y Hook, X = Sight Adjust (WC = Hitch) (WS = Slant)
56-57 2x2 [6 Man Slide] 2 Strong = Y Hook, #2 WR = Sight Adjust (W/WS = Hook) Hot may be Under (I.E. 56/57 Utah) Expect Mike Recall (2x2)
58-59 three step [6 Man Slide, Back Dual] Hot built in, Sight Adjust built in
62-63 2 Strong = Y Hook, X = Sight Adjust (WC = Hitch) (WS = Slant)
64-65 3x1 five step [6 Man Dual OL Read] 2 Strong = Y Hook, X = Sight Adjust (WC = Hitch) (WS = Slant) Hot may be Under (I.E. 64/65 Under)
64 Scan Protection Y Hot vs S-M-W Blitz = Hook, X = Sight Adjust (WC = Hitch) (WS = Slant) Can pick up Just 2 Strong with HB
66-67 2x2 five step [6 Man Dual OL Read] 2 Strong = Y Hook, #2 WR = Sight Adjust (W/WS = Hook)
68-69 Built in, built in
72-73 five step [5 Man SLIDE] 1 Back 1 Strong = Built in Hot, Poss: Sight Adjust built in or - #2 Weak off W/WS = Hook, Sight Adjust unlikely to occur, Expect Mike Recall
74-75 3x2 empty [5 Man SLIDE] 1 Strong = Hook by #3, #2 Weak = Sight adjust (Hook) Sight adjust unlikely to occur, possible Rita/Linda (Or Gap)
74 Rita-75 Linda 2 Strong = Hook by #3, W/WE = Hook unless built in, Possible Ram/Lion (Or Gap)
78-79 same rules, line shortens. Built in, built in
80-81 five step [7 Man Base Solid protection] No hots, X = Sight adjust (Slant/hitch) SA Strong (S/SS) = Z hook, Possible scan by gameplan
80-81 hot, Will/Weak End = H Hot (Diagonal) SA Strong (S/SS) = Z Hook
82-83 five step [7 Man Base Solid protection, Backs have flare control] No hots, X = SA Weak (W/WC, W/WS) Y = SA Strong (S/SS) = Diagonal, If Y Detached = Hook
90-91 three step [7 Man Base Solid protection] No Hots, built in
92-95 three step 2 back[7 Man Base Solid protection]
I didn't write that haha. I wish I could say I did. Essentially, you'd set up a play like such...
A running play would be 0 Ride 36.
Ride=A type of run
6=the hole the RB is running through (in my HS offense that was between LG and C, but it's different in every offense)
The play calling for passing gets more confusing, I'm not going to try to explain something I don't understand fully. Hopefully with this motivates you to learn what you wanted
