My man.
Personally, I've never understood narrow splits. I suppose it would limit interior DL mobility but otherwise it seems useless. I feel the same about the wide splits as well unless you have an ultra-mobile, ultra-talented line and you're carrying that throughout the entire field.
@ZRF said basically everything I've been trying to say. Essentially, we compress the field. Now, compressing the field isn't always bad if you have the right personnel. As a 49ers/Michigan fan, I've watched Harbaugh do it for years. What you can do with that is add a bunch of gaps in short space, therefore making the defense more shallow and delivering the RB to the secondary much easy. If you're blockers are really good at what they do, this is a nightmare for opposing defenses because you either have to have your LBs play conservative and allow 5-6 yards a lot or you play them aggressively and hope your safeties clean up messes on the regular. To me, our personnel doesn't seem to fit this. I'd much rather we looked at spreading teams out to give our line a chance.
I think for this offense to find success, they have to get more vertical. Route combos need to be much more varied in their level and we're going to have to put some DBs in conflict. Right now, they face no conflict.
