Tweaking traits

[Michigan Joe]

OK guys, we talk about tweaking for strength and tweaking for speed, but those who have played the game a lot may have some other key attributes that they look for to make the "athlete" (base + figure) a star. Other than pure speed or strength what traits do you look for in a base?

I'll start...I look for bases on my O-line that aren't just strong but "Sticky" by that I mean even if they get pushed back they regularly keep the defender engaged and in front of them.
