well i have custom playbooks. on offence i dont have any screens but thats probably because i get sacked using them on madden, no option. slants, crossing, pa, draws, runs etc. i form tackle over normally is this i think
TE2 LG C RG RT LT TE1 WR1
QB
FB
HB
Now i also use formation subs a lot, one to put certain attributes on the field or on Special teams to give non starters some playing time and avoid injuries.
in the above formation iirc TE2 swopped for LT2 or some OL backup, best OL spare with spd/agi/awr/rbk to TE1 and best RBK spd/agi/awr TE to WR1. now i might swop G/Ts depending who has best RBK/agi/spd/awr. its obvious im going to run but depending what their line up is you can audible to something like i form iso with fat boys.
as for defence, i play 3-4 and prefer lbs to dl. i stuff the run and make them pass. so coverage dbs is key.
i play 3-3-5 stack/4-2-5 normal versus option teams. 3-4/2-4-5/2-3-6/1-5-5 most of the time. depends on roster. prefer to play 2 deep man, but changing who is in hook or buzz or where pressure comes from.
mlbs for me need awr/prc/mcv/spd, olbs need spd/acc/awr. str/pmv on dline.
my starting rolb is actually a lolb 72 but they have higher awareness than my 77 rolb due to that awareness. you need to know who is on the field in each package and your depth chart.
nickel normal varies from 4-2-5 because the extra db is a cb in nickel and ss in 4-2-5. same with nickel 3-3-5 and 3-3-5 across
so setting up your depth chart (check awr drop for out of position) is important and then overlaying with formation subs. and depending on personnel doing the lb rush package in qtr defences may be an option.
stuff like that. my gf calls it fraculating, hours in from of the screen setting up the depth chart and subs each season. then again she does similar for skyrim
doesnt matter what game although some allow my penchant for fraculating, hc06/madden 08/hc09 etc. also depends on mantra, college throw the ball, regardless of sliders. my sliders assume thats what will happen, ARTs iirc. so stuff the run, force the pass, pressure the qb, commit to pass defence 3rd down. i might get only 2-3 sacks and no knockdowns but the 23 hurries mean im scaring him
im too old for stick skills, i was too old when decathlon came out for a pc at when you had to hit 5 keys for pole vault in 1985-6, took me 6 months to get over the lowest bar !
and as for rugby, the southern hemisphere refs and their let the game flow ignore forward passes id have thought you prefer passing to runs, its us poms who like to stuff it up the jumper (well some like northamption fans like me)
