re: This defense

Ok let's remove the adequacy of the the 2015 class and just focus on the player development of the 2015 class. BO has been the DC and in charge of developing that side of the ball for almost 3 years.

Who has he developed into a playmaker?

This is where I see the biggest difference in recruiting between Barry Odom and Gary Pinkel. Pinkel would pick guys with the athletic ability who needed to be taught the fundamentals and would come out as a better football player.

Barry Odom's recruits looked mismatched physically, mentally, and aren't making strides in development.

You can't make our LB's faster, that's not really a skill you can develop, if you're a 4.9 40 guy, you aren't going to suddenly become a 4.6/4.7 guy.

The current recruits on this team lack size, speed, and strength from a talent perspective.

The guys with it can't tackle.

That's the difference between a 30 something recruiting class and one that barely cracks 50.
