If you want to check out the DeMeco chat from the Chron, here it is:
A couple of interesting things in there. Here's what jumped out at me:
DeMeco_Ryans: Our running game is looking a lot better. You can tell by the changes Coach Gibbs has made to our running game. All of our guys are picking it up well. Chris Brown is looking the best. You can tell he is more familiar with the scheme.

Shake: From the defensive side of the ball, what specific improvements do you see in the O-line this offseason?
DeMeco_Ryans: Their techniques have been revamped. They're doing a lot more zone-blocking which will allow them to cut defensive linemen more. There are a lot faster off the ball. They do a great job of faking the run blocking when it's a pass.
I think that what I've bolded is the biggest change we will see with the offense. When I heard Kyle Shanahan speak on this subject when he first was with the team, he talked a lot about this. When he was with the Bucs, he actually tried to get Jon Gruden to change some of the offensive line blocking to make it harder to guess run versus pass.
He talked a lot about how defenses start guessing run because the blocking *feels* the same and then they get surprised by the pass and are out of position.
