If the Browns manage to get into the playoffs somehow then they won't trade Anderson next year. Anderson will start next year as the #1 QB. Brady will see the field eventually...he has too much talent. Sitting & learning for 2 yrs won't hurt him
If DA takes the Browns to the playoffs then Phil Savage will definitely cash in on the 1st and 3rd he'll get after they tender Anderson high. When you combine how prohibitive it would be for Cleveland to match a big money offer he would most likely get in that situation with the draft picks Cleveland would get out of it, you just can't pass that up.
The alternative for Cleveland, should they choose to delay the "decision" would be to give DA the franchise tag. If they do so without a long-term contract they risk losing him and getting absolutely nothing in return when he's an unrestricted FA in '08. If they do sign him to a long-term contract then BQ will not be with the Browns past '08.
The most likely scenario (in my humble, non-expert, not-on-the-inside opinion) is that the Browns take the picks to shore up the defensive line, sign a younger RB (Turner) as an FA and go with it.
This all hinges, of course, on Anderson not becoming this year's Rex Grossman.
