You can pretty much ignore the total rating. Some of the attributes, like WE, DUR, and ST, don't contribute much to your game performance.
On the other hand, your starters are all hovering at 40, or less, for DEF. That's a much more important rating and will more directly affect your results. Plus, almost 1/2 of your team was SIM-recruited. That's a recipe for disaster. When those guys have graduated, you should see better results.
