To be clear, your analysis shows that Mayo is already better than At and Seau inside and the O'neal roplacing Samuel is no big deal.
Well you know thats not what I mean.
And I did try to point out that I am not comparing player to player but overall unit to overall unit.
I consider Thomas at OLB better than Colvin and better than Thomas at ILB.
I consider Thomas at OLB and Mayo at ILB better than Colvin at OLB and Thomas at ILB.
I consider Mayo today better than Seau as he was last year at 39 years old, and actually dont think its even close.
I consider the improvement I expect in sub packages and 2 minute D to be more critical than the diminsihed play at the starting cornerback position.
I do not think that Asante Samuel did amazing things outside of the team defense that he played, and think that there is not a significant dropoff to a capable corner playing the system.
I think there is a tremendous room for improvement in sub and 2 minute D, and that we did not have a player grouping that was capable of excelling in that situation, but think that we now do. For example, rewatch the SB and tell me that Randall Gay has any chance whatsoever of staying with any wr in the NFL on a 3rd and 6 when the WR changes direction, and Gay has him man on man. You wouldnt ask Matt Light to play that position, and while Gay is a corner, he is so much less quick and agile than he needs to be for that role, he might as well be Light. (and the safety and LB positions werent quick enough either overall) I believe that this year we will be putting players on the field in those situaitons that are PHYSICALLY CAPABLE OF DOING THAT JOB, and last year we put players that were at best marginally capable, and physically limited.
That area of imporvement, assuming it happens, dwarves and deterioration I can envision.
I recognize that common perception is a starting corner is more important than the guys who come in for sub packages, but it is my strong opinion that for this team, the way it is currently put together, being better in sub and 2 minute D is more important than the play of one of the starting corners.
Perhaps that will prove to be wrong, but I can guarantee one thing:
We had a LOT more room for error in Asante Samuels play to GET TO the AFCC in 06 and the SB in 07, than we had for poor play in 2 minute or pass only D that cost us both of those games. Or in other words, there are an awful lot of corners we could have had in Samuels place and still been in position to win both of those games, and would have won both of those games if we werent horrendous at stopping the other team when they were in pass only situations.
