Bret Favre, tired?

A lot of chatter has gone on about Bret Favre against the Packers. The numbers show the Packer quarterback had better stats except for the interception but the rest of the team did not play well, missed tackles, dropped balls etc. No one says Favre is a bad quarterback the problem will be during the important games at the end of the season Favre will be on the sidelines with a tired arm just when his team needs him on the field ala McNair, and McNabb.
