Let's try a more minimalist apporach. Let us presume that Ninkovich pick ups the reps of Thomas. Please compare.
============================================
2010 BANTA-CAIN vs 2009 TBC even
2010 WOODS vs 2009 WOODS even
2010 MAYO vs. 2009 MAYO improvement
2010 GUYTON vs. 2009 GUYTON even
2010 BURGESS vs. 2009 BURGESS slight improvement
2010 NINKOVICH vs. 2009 THOMAS loss (certainly not a huge loss from 2009 Thomas)
=============================================
WITHOUT ROOKIES
I am saying that the improvement over 2009 by Mayo and Burgess will be more than the loss of moving from 2009 Thomas to Ninkovich. Do you disagree?
===============================================
THREE YOUNGSTERS GIVE THE POTENTIAL OF SIGNIFICANT IMPROVEMENT
If any of McKenzie, Spikes or Cunningham has significant impact, that will be a major plus.
===============================================
BOTTOM LINE
I do NOT count on rookies, except to believe that Spikes or McKenzie or Spikes will give us what Seau did in 2009 (injury protection). I agree with everyone that we can HOPE that Spikes or McKenzie will start, moving Guyton to a backup role. We can HOPE that Cunningham will take most of the reps of Thomas with at least similar production.
I think that this is the patriot way. We expect to improve a bit, even without any rookie production. And if we do indeed get rookie production, we could get much better.
=================================================
I think that expecting much more from Ninkovich is probably wasted hope. I think that expecting TBC to repeat last year is probably going to lead to disappointment. I expect that improvement will have to come from:
Mayo
Spikes/McKenzie
Burgess/Cunningham
That means that you're counting on 3 rookies, one guy who was a stiff last year, and one young guy who's coming off of a poor season, hopefully due to injury. I'm not saying that they can't make the LB corps better. Given what a load of garbage the LB corps was last season, the bar's not exactly set very high, after all. However, I am saying that you're expecting a lot of "if" players to come through with very positive results.
