Egvrich, we are in a division together, so if you are talking about my team, I can give you my perspective for what that is worth.
First, I agree with Scorehouse. Unless I see a particularly favorable matchup for my starting pitcher, I tend to set my starters for max 6 or 7 innings. I do have one complete game (very proud of that!) this year, and wouldn't mind getting a few more!!!
Anyway, that seems to get my #1 reliever (whoever is my #1 reliever) in to the majority of the games.
As far as Wilcy Moore, he isn't my favorite #2 reliever, but I like him. Given your team has a lot of power (you are #3 in Home Runs and slugging pctg league-wide), and that you are in a power park, and that another divisional rival has a high batting average team (.295/#3), I felt an R5 might help in instances where my starter got knocked out early. I'm not 100% sure it was the right call to be paying for the high duration, given that some other more effective R2s and R3s are likely available at the same price-point, but I guess it was a kind of insurance to avoid having my less #3 reliever (or worse, anyone beyond my #3) see many innings. I'm not sure, actually, about Wilcy Moore. I think I would draft elsewhere in a similar team-design.
I'm also unsure about Murray. For my home park, Hoyt Wilhelm might have been a better choice. None of the divisional opponents really steal bases, so paying for Murray's -5 hold rating is a cost that isn't put to good use in this context. HW would have let up a few more home runs, but his WHIP would be far better. And he has fewer errors than Murray, too. In no-DH leagues, HW is an "A" bunter, where Murray is a "D." As far as Murray in this particular season, there is no way he will keep up a 2.3 ERA the whole season, or if he does (very unlikely), it will be a major outlier.
I think your team is good, very good, but I'm not sure I would have dropped Matthews for Thome. I guess that might work, depending on the percentage of RhP, which I have not looked at. Your run differential, and your prowess at home, and against RhP, are all very impressive!
