I see you've begun to build the hard-hitter SA tree. Does that mean you're building an MLB? If so, once you've triple-capped agility, you need to immediately begin tackling/strength. You should be training them on intense right now as you build agility. If I'm being honest, you have kind of a goofy build, but before you go ANY further you need to decide which route you're taking the build (OLB/MLB).
Don't you dare say you're going for a "balanced" approach. "Balanced" LBs are fail, and find themselves mired deep down on the Depth Charts at all levels of play. MLBs need to be very strong and great tacklers, and very agile. SA's in hard hitting tree, focusing on building defense general. OLB's need to be very fast/agile/high vis.
So choose a route, and go from there.
