Mid April - Teams may begin official off-season strength and conditioning programs, limited OTAs, etc.
Late July - Full training camps begin
Here was 2010's offseason but it will be different like you said:

There will be a lot less practices... a lot less days in pads... less practices per day but last year coaches/players said 1 3 hours practice is more beneficial than 2 or 3 practices per day at 1 hour or 1 1/2 hours.
