I have a feeling his knees won't be able to hold up over a full season if he were a starter. The one play were he stumbled, or his foot was stepped on, and his knee went into the turf, you can see him grab at his knee. Maybe with more time as a backup, they will get better.
I think a better comparo is to Drew Brees rather than Chase Daniel. His ability to read the defens is pretty great.
