At lunch I went back and watched Siemian in the last game, particularly the last part of the first half, since that's where the bulk of the "wow" came from.  I saw some stuff that looked like improvement, but I also saw some stuff that looked like last year.  First two plays during Siemian's work were runs.

But, the next two plays were last year's Siemian.  First resulted in a first down, but if you look what Taylor was doing, he was wide open in that same area and it could've been huge.  I think on that play Siemian locked on Henderson (maybe).  First down, but opportunity lost.  Next play there was pressure, and Siemian ended up getting flushed and threw it away.  But, Henderson broke into the open in the center, and Siemian could've dumped to him, with a pretty open field.  

Hoping the game slows down for him, cause it looks like with this team, the opportunities will still be there even on broken plays. 
 Gonna be interesting, for sure.
