Extend Ingram NOW!!!
As much as I am enjoying Ingram's success, he might just be in that strange position where it's highly unlikely that he is a Saint next year. $5 mil is right at top 5 RB money. Is Ingram a top 5 RB in the NFL? Funny question until you see who is currently listed in that price range: Foster, Spiller, Gore, S. Jackson, F. Jackson, Greene, Richardson, Matthews, Moreno, D. Williams, Powell (lulz?), Helu, Rodgers, Murray all make more than Ingram, along with the top guys Forte, Lynch, McCoy, & Peterson.
Remove AP, because he may never see the field again. IMHO, that puts Ingram right on the top 5 cusp. Which means $5 mil. Which the Saints already declined. Now maybe they knew what they had and were hoping for a perfect storm where they could keep MI for cheaper than market value. But he seems to be outplaying that.
All of that said, you generally don't get better by letting guys who are top 5(ish) at their position and in their prime walk for nothing.
