Will I miss IS?

I am looking at upgrading from my 55-250 to the 70-200 F2.8. I am weighing the options of getting a new 70-200 2.8 non-IS before the rebates go away or trying to find a MK I 2.8 with IS used for around the same price. Right now I use that lens mostly for kids track and football and want the 2.8 for shallower DoF and to allow in more light for friday night football games. I also do a little birding with my other lens. It is not ideal but it works.

For those who have the Lens with IS do you use it at all? Since I am looking at using it for sports I would have it off.

Will it be missed if I go with a new lens without IS?

BTW I shoot on a 60D.
