Great thread! I think of this as a D that can be run more than one way. But, how I tend to run it is as more of an aggressive, man-to-man defense. I like to try and keep a guy deep (when possible) but am not afraid to go zero coverage either as I'm convinced that my particular team will get to the QB very fast.
Most teams that are running the 3-3-5 don't have the most incredible personnel to run it. In that case you don't want to blitz QUITE as much, you want to bend but don't break most of the time, but turn it up and go for the big play sometimes too. As San Diego State, recruiting hasn't been easy going. My best players have been transfers. So if you are building up a team I suggest cutting to around 68 players to leave room for a couple transfers.
Lean on the JUCO players if you need to, there are some BEASTS and usually the CPU will not go after these guys until late in the year. Once you get the prestige then you can go toward more traditional team building. I have uploaded an image of my roster and I will talk about each position, how it either fits my mold, or somewhat doesn't, or if I'm just looking to replace the guy. Note, this is in the year 2016.
These are just my starters. Note that it's a pretty young team overall, I have never been an OVR guy I go by the other ratings for the most part but I highlighted OVR and then the important ratings (for me) for each position are highlighted yellow.
LE Bennett - I have 3-4 DE's with better OVR ratings than him, but he is a man beast who is going to do nothing but get better. The size is just perfect at 300 lbs. He already has 2-3 sacks and has caused fumbles, I think of this guy as a poor man's Reggie White. He is exactly what I want at the position.
DT Bradford - JUCO recruit. Redshirted one year. 4 sacks in 3 games, just dominating early in his career at SDSU. HUGE and STRONG, with sufficient ratings at all the important categories. Exactly what I want, but I want a freshman one! lol. Don't worry about the lack of speed. At the range they are at the ACC is all that matters and he ragdolls blockers and eats up the play in the backfield.
RE Jordan - he's been very effective. He is not the optimum, I'm recruiting a JUCO monster that might take his place next year that's 6'4, 280. Can't always get the perfect guy for every position, he at least has a lot of what we require like the block shedding, pursuit, and pass rush moves.
LOLB Knox - He's a solid OLB. We'd like more of a pass rusher here, and we'd rather have a 6-2 or taller guy. But while size is nice, it is not totally necessary. It's more important for me at SS, where they will be playing man coverage on the inside routes or playing zone in a position to use their size outside the hash.
MLB Newell - I was worried about his lack of speed (had a really fast guy last year) but I can already tell Newell is going to be exactly what I want at the MLB position. Quickness (ACC AND AGI) are very important. They play in the pile a lot. For the defense to be really effective he needs to be a good pass rusher and with 84-85 pass rush moves, he fits the bill. Has 3 touchdowns scored in his first three games, two FR, one INT. Basically I'm looking for a Vilma type here. Better size would be nice, but isn't necessary.
ROLB Daniels - Well what can you say. He's an absolute MONSTER. He transferred over. It was tough him sitting out a year seeing his ratings rot on the bench. But they get an EXTRA year of improvement that normal players don't get so transfers turn out to be awesome a lot of times. He's exactly what I want, a Derrick Brooks type. Man coverage is key so that you can free up your strong safeties to blitz sometimes. He is adept at man and zone coverage. Sucks we lose him, but we have a kid that will be almost as good (eventually) that we are about to sign.
CB Miller, Vaughn - I play a blitzing, man-to-man defense and so I need awesome speed and acceleration. While size would be nice, the speed to keep up is much more important. Nobody can get open against these two and they're just sophomores.
SS Mangum, Coleman - In my defense (the way I run it) I want man coverage guys. By sheer coincidence both of these guys are horrible in zone but typically when I play them in zone it's pretty basic stuff. Drop deep or play the flats. Suffice to say their strengths make up for their shortcomings. In this game these are almost always converted FS's, and both of these guys are (because the SS's are too slow). Young had a better zone coverage rating so he stayed at FS, and I moved these guys to SS. If these guys are fast and can play man, then you don't have to come off the field EVER in a 3-wide set and sometimes even when it's 4-wide. Sometimes I'll blitz both even against a 3-wide, then manually have the closest SS cover the slot then hot route the OLB that was on him to blitz. That way I'm sending 5, an OLB, SS, D-Line, and have a FS deep with great coverage on the slot.
FS Young - The only guy in the Defensive backfield who isn't playing man defense most of the time. He has to be a good tackler. In over 2 he will often be playing in a great position to make a big play just behind the linebackers. Good play recognition and awareness are really key, as is the zone coverage rating. He doesn't have to be a burner, but if he is, that's great. Note... In run stuff situations he becomes almost like a middle linebacker. You will be run blitzing and he will usually be on the HB. His job will be to aggressively fill whatever hole is left. For me, the block shedding isn't too important for him because he's usually the guy that comes free.
