I just bought the Malcolm Butler 90 OVR HERO to use in his power-up set, wow, he is a monster. By far the best CB on my team, and not too much worse than some of the other top corners in MUT. Go compare him to the full Legends Deion, and you will set they're very comparable (minus Traits).
This was a much needed improvement for my defense, which is pretty bad at times. I am still hoping we get a new Patriots Legends card soon, hopefully either Tedy or Willie Mc!
