showboat blocker if you get pancakes
red zone freak if you get your entire team in on it
+0.3% strength if you are a beast and want to abuse your push
+0.5% vision if you don't have a mentor as it looks like vision is becoming more important
goal line blocker if you are having major push-it-across issues for some reason
clutch if you force starters on third down and are one of them..
heart of a champion if your team is a playoff lock but you know you'll be facing some beastly guys across the line in the playoffs
second wind if you don't have a line general at C and are ending the games in the 70s energy and don't want to push stamina up right now
slow starter if you get a lot of snaps and your team can afford avoiding your player in the first quarter (ex, rush right all 1st quarter when you are LG, so you aren't a big liability, then switch to left slams in the second half)
People get annoyed when owners try to control player builds... but I think my above list basically highlights that VAs being successful depend entirely on what your team does and what they want from your player. Ask your owner and listen to him!
