I used to stay clear from these guys because I felt that my diamond/gold round picks should be players used in every game no matter the pitcher. However, I ended up choosing a strong gold reliever most of the time (Wagner, Smyly, Benoit, Rodney). I like having 2 silver or better rightys and one lefty usually, but I'd still get top silver options later and have too many good relievers.
So I finally took Sizemore one draft and only played games when facing RHP. I'd back out when I saw LHP. I hated players who did that, until I got 12 wins, with Sizemore hitting 9 HR in 14 AB. I also would have him bat lead off, so no matter what he's face a righty at least once.
I've been doing that ever since and it's worked extremely well for me. I have FB Eithier this draft, in 4 AB leadoff, 4 HR. Considering most starters are bronze..it's a great matchup that can't be avoided. It also seems like most of the Gold Flashbacks have incredible stats vs either leftys or rightys, and crap for the other. Nothing in the middle.
Anybody else have success with this strategy? Like I said, I initially hated players who backed out while adjusting lineups...but if its going to give me a better chance for a rare flashback that I can't buy with mommy's saved credit card info like half of players...I'm gonna do it
