Your league size would help..
A lot of your players just have not started out hot.
Although,I would dump Betances for an actual closer,& Ramirez for another SP.
I have been trading for Kris Bryant & Anthony Rendon in a lot of leagues..
You should also try for them.
Their trade value is as low as it will get right now.
I have been getting them by trading away 2,or 3 players for each of them.
Rendon & Bryant,I think,could each be fantasy beasts very SOON.
Another player I have been going hard after is Kershaw..
Kershaw has not been his usual dominant self as of yet.
Before dumping Ramirez,I would actually offer Ramirez + Sale for Kershaw,then pick up another SP off of waivers.
BTW-A lot of my teams have 0 offensive backups..
This makes me dominant in wins,saves,& Ks.
I trust my high QUALITY hitters will win me offensive categories,so I can win pitching categories with a high QUANTITY of pitchers.
I think your offense will start hitting soon,hang in there.I would designate Rizzo untouchable as far as trades,Rizzo should be a beast.But,everyone else could be used as trade bait to get higher ranked HITTERS & a larger quantity of SPs & closers.(I believe Betancourt has just become the Rockys closer.)
