Only time will tell at this point, but part of me is thinking, if all these teams were able to work Peyton Manning out and were satisfied with his progress, why would the Colts release him.
Yes, I know when he was out the team sucked and they needed to rebuild that team because they were horrible all around. But if I were the GM. I would have kept Manning and rebuilt around him, thats one less BIG hole to fill.
Think about it, if they decided they were keeping Manning, it would probably mean they did not want to pick Andrew Luck. That means they would probably be open to trading out of the #1 pick. Imagine how much easier it would be to rebuild if Washington was willing to give you 3 extra 1st round picks over 3 years and whatever other picks they sent to St. Louis for the 2nd pick. If you are worried about trying to compete NOW and not in 2-3 years after these new draft picks learn how to play in the NFL, then trade those 1st round picks for established young up and comers in the league.
Maybe Manning's arm is done. But a big part of me thinks it isnt, and that part of me also thinks that the Colts were idiots for cutting him loose.
