Save for those owners in wacky 17-week fantasy leagues or those prepping for an elimination-style playoffs league, all of us already are turning our thoughts to the 2007 NFL season.

So let's do just that.

With a few exceptions (hey there, Seattle), the offensive line turns out to be the best place to start when determining whether a player's value is on the rise or in decline. Scheme and coaching changes occasionally can shake up an O-line (in a good way), but age, durability, depth and stability are even more crucial. Keeper leaguers will find the analysis below most helpful initially, but others can read up to get a head start on '07. Never too early to start boning up for draft day.
