First: When can I offer contract extensions?

Secondary: Can I offer extensions to all players, regardless how many years left or is it only for players with 1 year left?

I'm pretty sure that you can sign extensions whenever all throughout the season and even the offseason to most players regardless of whether they have 1 year remaining or 5 years remaining.

Players that you aren't able to sign to extensions are: Rookies, Players signed to 1 Year Deals, Players that were just recently signed to an extension, and ALL Players during the 1st year after an allocation draft.

Oh right.

So no contract talks until next season. Thanks. :)
