A few qualifiers...
1. The player's keeper status counts. There's nothing wrong with keeping someone like Eric Byrnes off last year if he costs you one slot. If he costs you three slots, you're getting called out.* * *
3. Your team's roster construction counts.
Given B.J.'s crappy 2009 and the team's choice to keep him over Jayson Werth, Joakim Soria and Anyone Else, Mr. Upton's selection makes sense. Congrats B.J., and here's to a fabulous 2010.
