Those are insane categories for a H2H league, just so you know. Fielding percentage, hit for the cycle? And I don't even know what "A" or "OFA" stands for. Why not count Webgems Allowed or Unassisted Double Plays Turned?
Sorry for the tangent, I just am really not a fan of leagues with random categories.
Anyway, your question: Why do you want to drop Swisher "for sure"? He's lived up to his reputation as a solid OF2 with good production across the board (except SB, and if you drafted Swisher for that, well....) I'm not sure the other players you mentioned are better, honestly. Jennings has more speed and has been hotter over the past couple weeks, but he's been worse overall.
I like Jennings. Has finally starting playing well this year and he is on a team that is getting hot and playing for a playoff spot. I am considering dropping someone for Parmalee myself. He has been playing really well but it is a small sample size.
