I agree that your infield could be improved upon...but I would keep Lopez in addition to Ortiz. Lopez is very solid. I would definitely get rid of Kendall. He is SERIOUSLY overrated. Catching is thin enough that I think you could trade him to someone else in your league that would overrate him. I would look for a different 2B and move Lopez to SS. You could probably trade for Cano, Weeks, Loretta, Iguchi w/o having to give up too much (getting one of the premium 2Bs will cost too much)
I would keep your starting OF intact, but wouldn't hesitate at all to trade Casey, Guillen or Alou (c'mon...that guy pees on his hands!) along w/Kendall in order to upgrade in the infield. Bobby Crosby, Orlando Cabrera, Bill Hall, Ryan Freel might be had at a reasonable price. I would also drop Counsell FLAT. He will bring some SBs...but isn't worth the roster spot.
Your SPs are very solid...even if they won't all give you great ratios (Mussina, Lowe), they should give you a decent amount of wins and provide solid numbers across the board. Sheets and Pettitte are very strong and I think that Weaver will pick up some W's for the team with the longest name in all of sports.
I think your RP situation is PERFECT. Two very good RPs is a good start...just be ready to pounce on the waiver wire as soon as teams make RP changes. Valverde has some FILTHY stuff...he just needs to stay healthy. He should give you good ratios and save as many games as you would expect for a team that isn't very good. I would drop Hermanson though...he won't be picked up, so if he does somehow end up with the closer job again, you can be the first to grab him from the wire.
