BeAllEndAll: Your squad was quite a challenge to dagger. Very well setup in terms of balance and depth. So, I'll start with the Second Dagger and take out Dodger Stadium. I don't know if that actually hurts, though, it just means you'll have to pay a little more attention to some of the finer details in drafting your team.
Didn't feel I could take out any of your pitchers as your depth there would have whomever was daggered replaced within a blink of the eye and without any impact on overall pitching quality. So, I felt going after a hitter was the best option. You have depth here, as well... and for a minute I thought the best solution would be to dagger one of your <$1m backups as it would then force you to waste about $1.5-2m on your second player for this particular position.
So, in the end, though you have some solid replacements, I thought losing Bobby Grich would end up having the biggest impact overall because of his cost effective offense+ defense. And now you have to spend more $/PA for either a worse bat or a worse glove.
Good luck, you've got a solid squad!
