3 things/changes I would implement before the start of the season.

This is kind of like Bruce Almighty w/ the power of god, but you wield the power of Mack Brown instead.
Who knows, maybe some of these will actually happen and I'll look like a sage.

Changes that need to be made.

1. I'll start with the most controversial. Move Sergio Kindle to RB. It seems like anyone that has gotten a peak of Kindle, 3rd hand comments from coaches -- and what we've seen so far would indicate Kindle may not pan out at LB. Sure this a premature knee jerk reaction, but its the offseason. As head coach I would wait and see if he shows any progress through the summer, maybe even the first game and then pull the plug on his defensive days if things aren't clicking. It isn't like Sergio is an LB or die type player. He was an all-world RB in high school. We caught a glimpse of his potential in the Alamo Bowl and I like to see what he can do. RB is the easiest position to learn and transition. Wasting another sub par performance year at LB would be a shame.

2. Mix up the secondary with young and old. It never ceases to amaze me how Mack can reload the DBs by slapping another round in the lineup each season. I go in to every season thinking, "so and so will never be as good as the last guy." Wrong. Akina deserves all the credit, but Mack and his  staff do an excellent job of developing DBs in to primetime players.

For years I ragged on my favorite whipping boys Huff and C. Griffin and look how they turned out. Hell, Griffin may even be the best D player on his new NFL team. Who saw Ross as a future Thorpe winner in 05? Not me.
So I say give the older guys a chance, because recent history proves they are going to be solid -- but mix in the young guys at safety and sub at corner.

3. Make GD pass the ball to JC more. Not just screens either, but hit him on routes and out in space. Is it me or did he look like the fastest player on the team with that wheel route against Iowa? Why did GD wait an entire season for that? He should still run the ball, but increase his touches with more activity in the passing game. If GD refuses, I will fire him......or maybe not.
