there are usually a couple sites with this info. just search for 2006 free agents. it is hard to come up with a comprehensive list because many players sign one year deals or have options and that kind of stuff. anyway, this should get you started. it was made in nov. so guillen is still listed with anaheim and there are probably other changes.

there have been studies. i think we discussed this last year so you can search for that thread if you want to read it. if i remember correctly the studies showed that there isnt any league wide significant improvement when players are in a contract year. if a particular player always does significantly better in a contract year then feel free to incorporate it into your rankings. however, merely noting that player X is in a contract year does not mean that he will do significantly better than prior years. people seem to remember the 2004 adrian beltre but forget the 2003 miguel tejada.
