Personally, I don't think the software is worth it. You are really on paying for projections and simple arithmetic functions, and who says the SW's player projections is any better than others. Plus, paying $40 for SW on top of an entrance fee of e.g., $30 means paying $70 to try to net $200, which makes no sense. Injuries and only 16 games make FFB much more of a crapshoot than say FBB, where stats typically average out over well over a hundred games.
My favorite strategy is the old manual calculation method to come up with my own draft list: after reading the news on players for the year, I try to compile a list of player value with respect to the league's scoring rules irregardless of player position. I believe some call it the X-Factor or X-Rating or whatever. But a simple version is:
Determine from stats you trust what the yearly fantasy point total is for each player. For example, if Tom Brady projects to throw 4400 yards, 30 TD, 10 INT, in a 6 pt per TD, 25 yds passing per pt, and -2 pts per interception league, then calculate 4400/25 + 30*6 - 10*2 as Brady's yearly fantasy points projection.
Once you get the stats for each of the players, determine how many of a position is to start in your league. For example, twelve QB's may start. Thus, determine from your list the 12th best QB. Then subtract that 12th QB's projected pts from every QB's projected pts. For RB's, if the league starts 24 each week, then determine the 24th RB projected pts and subtract from the rest. Once you determine the difference for each position, you can compare the final numbers irrespective of position. Thus, you could compare LT to Brady after subtracting the 24th RB from LT's points and the 12th QB from Brady's points.
This gives you a master list.
This may sound like alot of work, but it is VERY easy. E.g., CBS Sportsline and other sites output their player projections to an Excel spreadsheet. Then you can use a quick formula in Excel to calculate values. Takes me less than thirty minutes to do this calculation part.
Now if you are playing in a performance league, then obviously this will not help as much.
