I think the Saints should increase the offer to $20 million a season, but NOT an average of $23 million over the first three seasons. Brees would average more than Brady and Peyton under such a deal. The $23 million is ridiculous, however, especially when we take into account just how much one injury can take a player away for an entire season. See Manning.
And the interesting thing is this--Manning's deal averages $23 million in the first three years but not for long. If rumors are correct, Manning will be cut.
