I see less reason to have high GPP out of season. Really work maximal strength, power output, speed, and agility during the off-season. I see Option 1 as being better for this.
About six weeks before games start, you need to get them in game shape, so fire away with the GPP. Scale back as needed during the course of the year. Option 2 seems to fit the bill. Explosiveness should be getting worked sufficiently with in game / standard practice stuff.
