The team needs another Amanar. Aly is the 2nd best vaulter on the team, but her vault looks worse than 4 years ago when she was the first vaulter up in prelims. If Maggie can get an Amanar, she'll be picked over Locklear for VT, FX, and AA potential. But right now I agree that it's Locklear.
I don't consider her a shoo-in for an UB medal like I did a vault gold for Maroney in 2012 though, that'll be the difference if they go with Maggie for extra cushion on the other events. Maggie proved herself on all 4 in TF in October (and won an individual medal), so she's still got that spot until she gives it away IMO. NBC seems to be pulling for her also..
