Rams will be in a tough cap position next season. While I see we are projected to be a couple of Million under the cap next year that doesn't include the salaries for any of the potential FA.
Losing 2 starters on the Offensive Line would be tough so that will have to be a priority either for resigning Hav's or Edwards or at least using a couple of draft picks.
Losing 2 out of 3 starters on the defensive line is also a big issue even if Bobby Brown steps up. Again another position that will be a focus on a key resign or drafting.
While there are good players that are FA at other positions I think we have the developmental players already in place that can can fill the holes and will be seasoned with rotational playing time.
Matt Gay is good not great so you are going to have to spend some cap money on a kicker regardless of who it is. Preference would to be to keep Gay providing he has a good season and a reasonable cap number.
