Jumping and stamina (super important attributes for getting pt and swats) are next. After those get to at least forty (or even maybe capped), work on tackling and strength to the first cap before going all out speed and agility for the rest of his career. My build on my SS isn't open, but if you look at his bars and stats you'll see that I kinda know what I'm talking about. People don't appreciate strength and tackling enough for SS's, and those two shouldn't be a point of emphasis, but you HAVE to get them to a certain level so that you don't get bowled over every time. By level 45 aim for 48 strength, 48 tackling, 90-something speed, 70-something agility, 40-something stamina and jumping, 30-something confidence, mid-20s catching, and at least 60 vision. Hope that helps.
