This. Depth is WAY better now than under Mac. I remember when Mac signed Leaders and Curvey. Those two were basically four year starters who played every down of every game. Berryman would have been a four year starter too if he hadn't gotten in trouble. And there was no one behind those guys. Conversely, CPR brings in a JUCO DL this year not to start, but to be the 4th DL in a rotation and possibly compete to start in 2012. I think that CPR has better depth at RB, OL, DL, DB than Mac or Chizik usually had.
My one complaint is at WR and TE. IMO Mac had some nice WRs with the Danielson/Whitver/Young/Montgomery group and then the Blythe/Davis/Flynn/Sumrall/Hamilton group. They've went downhill since then. Neither Chizik nor Rhoads has been able to recruit a WR that would challenge for a spot in either one of those groups. At TE, CPR started with Catlett/Franklin/Hammerschmidt. Now it's just Hammerscmidt. There hasn't been a good plan really to replace the other two or fill the pipeline other than the JUCO Brun and hoping Pierce Richardson develops.
Overall, I think that the starting talent is fairly similar, maybe slightly better, under CPR compared to Mac and Chiz, but the depth is better for the most part. Out of the three staffs, I'd rate them like this:
Recruiting
1.Chiz
2.CPR
3.Mac

1.CPR
2.Mac
3.Chiz
Grades/Legal issues

3.Mac
I am not saying that Mac wasnt a good motivator, I think he was. I think that CPR is just as good ( I have obviously never been in the locker room to hear either of them except for the CPR vs NEbraska viral video). I would also argue that CPR's playcalling on the field helps to motivate his players during the games. I mean as a kid would you get more pumped when your coach strategically calles 2pts conversions and fake punts/FG's or if you knew that a 3rd and long would be a draw and a punt?
Other than that small fact I would agree with the rest of your ratings
