i wouldnt recommend nickel sub or 1-5-5 at all this year. just not effective. i like to use 34 solid and 34 normal with them, but here ya go!
my 34 Setup:
LE-Cesaire(best player left to fill LE)
RE-English(90 overall DE, 84 power move+89 finesse move+82 block shedding)
DT-Castillo(increases 7 points at DT, and 96 block shedding)
LOLB-Shaun Phillips(no explanation needed)
MLB-Barnes(86 SPD+92 ACC), Butler(84 SPD+93 ACC)
ROLB-Applewhite(82 SPD+87 ACC)
CB-Cason(87 MCV, 85 ZCV), Jammer(93 MCV, 88 ZCV, 96 Press)
FS-Watkins(i user him)
SS-Weddle(he just makes plays)
If you want to have a better player at MLB, put Stephen Cooper in for Barnes, and put Barnes at LE. I just like having all that speed at LB so i can mix in man a few times every game, with safety help over top of course.
