Not sure folks here really understand what the market comps are for a player like Bradley.
I would not be surprised if he gets an offer north of 7M per. As Crimson points out, that's kind of the going rate for that kind of player.
Can you provide some examples?
If you are looking at shooting guards who got contracts last off-season:
Kevin Martin - 4 years (including player option), starting at $6.5m
Monta Ellis - 3 years (including player option), starting at $8m
Gerald Henderson - 3 years (including player option), starting at $6m
I know some people disagree with me, but I would rather have Avery Bradley starting at SG rather than Henderson. It's more controversial that I would take Bradley over Ellis. A lot of people here who think Martin is better than Bradley would probably prefer Bradley because he is younger with upside (and I think you are just flat-out wrong and almost not worth debating with if you think that Bradley has plateaued and there is no way he gets better).
Henderson was also a restricted free agent supposedly looking for more and reportedly gave up a million per year to get that third year to be a player option.
I think the options regarding Bradley look something this:
lowball fully guaranteed four-year deal
four years for more money, but the fourth year guaranteed for no more than $1m (or a team option)
three years
three years for more money with a team option for the third year
three years for less money with a player option for the third year
