I don't disagree with you on any of your points.
I always like to read the opinions of people that aren't as close to the program because they sometimes see some things that we don't. As a Minnesota fan it is easy enough to see fault in the rest of his rankings to determine that I don't want to put much stock in his opinion whether it is good or bad.
Any ranking that doesn't put Brewster and Zook right next to each other at this time doesn't make much sense to me. From what they have shown on the field they are fairly comparable. Undoubtedly they are both good recruiters. Zook finished second and got in to a Rose Bowl when they should have been in the Capital One Bowl which is his greatest accomplishment and outside of that they have underperformed. Brewster took a team one year off a bowl loss and 6-7 finish that lost some key players and finished 1-11 before rebounding in year 2 with the help of a great class to return to the same bowl and a 7-6 finish. The rest of the story has yet to be written.
My ranking:
1. Tressel (They have won or tied for the conference championship 4 straight years)
2. Paterno (Too much accomplishments to not honor him)
3. RR (Credit for success at WVU, if going solely on Big Ten he ranks 9 of 10)
4. Ferentz (He has had some very good years but also inconsistency)
5. Dantonio (too early to really know, judging from 2008)
6. Fitzgerald (too early to really know, judging from 2008)
7. Zook (Recruiting success, general underperformance
8. Brewster (too early to really know)
9. Bielema (too early to really know, just making a call--judging from the trend line)
10. Lynch (too early to really know but I have yet to be impressed)
Not ranked: Hope
#5,6,8,9,10 will all move around a lot over the next 2-3 years because we have seen very little from the 4 of them.
