No need to prove anything.
Texans offense was terrible saved for Pierce.
But that was mostly because of Mills (and any other QB the Texans trotted out there).
Pickett did more than Mills with less.
He had a worse offensive line and a worse situation at RB.
The Steelers coaching staff had firmly said that they get their QB.
Knowing the guy as being a good HC; I believe he knows what he's doing. When Tomlin says Pickett is good enough for him, who am I to disagree.
You, TK, on the other hand, has only words.
