I've had solid diamond players in my own most of the year. I've used Blake Treinen as my closer (his gold card) till I hit 100 saves with him, then was going to just use Hoffman SS to close. Just so happened they released a Blake Treinen 90 overall diamond, so I'm using him to close now because I really like pitching with him.
I haven't invested much time effort or money to build my bullpen. Every pitcher in my Pen, with exception of the 90 overall Trienan, I pulled from a pack. I was going to sell the Diaz 94 card, he sells for a pretty good price (around 30k last I saw) but I've come to really like him. I bought Chapman too (but that was more so I could finish the Yankees team collections). I didn't know he had an all-star card til the other day. I got Brantley and Muncy in my all-star pack when I completed the moments.
I was thinking, since I've got so many starting pitchers that are diamonds that I don't use anymore, I'd sell them off, using quicksell for most of them since I got them in pack or bought them to finish off collections. (Still have to finish the Angels, Indians and Red Sox to finish the AL and get Pudge. But I have Carter behind the plate now, so spending that much money/stubs to complete those 3 teams, well, 3 players, 1 on each team that I won't use except maybe Trout just doesn't seem worthwhile)
I like the Hoffman SS card, but rarely use him to close. I had Billy Wagner, but sold him after I got him (got over 140k for him) so I could round out spots like 3rd with Brett, along with SS Hanley Ramirez as kind of a utility bench player. I did enjoy pitching with him, but at the time, he was a stub lotto ticket. But now, I've got my rotation fitted nicely, although there's a couple of guys I'd still like to get, like the Oswalt SS. I rocked with his 89 ovr card, and enjoy pitching with him. I'm still trying to pitch with Hershieser (I waited to finish off the Dodgers collection, and I'm glad I did. Jansen went from diamond to gold, and his price went from mid 20s to 30k at certain points, I ultimately paid 3k for him. Didn't HAVE to get Kershaw because I've got his SS card.) so after I finished the collection, I quicksold the Kershaw diamond card.
I just wanted to round out my main lineup and staff with all SS cards. So I want to finish up the bullpen. Then I'm going to try to build a lineup/pitching staff of the rewards cards from moments. That's going to blow, because I sold a lot of them chasing down certain cards. I may sell Griffey Jr, I am not sure (I've got the SS Torii Hunter card I can play in center). Just so I've got the stubs to rebuild a lineup and pitching I got rid of and will have to buy back. Not sure how I'll go about it. I have pitched with the AL/NL all star teams in one of the moments, and did like pitching with the Dennis Eckersley SS card, but was tepid with the Rollie SS. So I'm going to be looking...
I appreciate the help and replies. If you can think of any SS relievers that you really enjoy using, please let me know who... So I can check them out for myself. It sort of irks me that we can't even quicksell, or list guys earned like Bartolo Colon signature series when I know I'm never really going to use him. Ice pitched with him a few times, and he's just not my cup of tea. I don't use the Nolan Ryan sig series card either, because both of them have some control issues. So they just sit there wasting space, and not giving me the loot I could use to go after other SS RP'ers.
Again, really appreciate your inputs and insights to this. So please, if there's anyone out there who has a SS RP they really like, let me know, because I'm open to all ideas. Just a small aside (from the manifesto looking post this is) Percivals SS and the Miller SS (from the extreme moments) are the next 2 on my list. Almost bought Percivals card right after I used him in the Guidry SS moments (with the all-star games at the bottom) and I really did like using him.
Edit: I am surprised that you don't care for the Hoffman SS card. I like the selection of pitches he has, and his ability to change speed. Especially with that circle change. I forget how I got his card, or where, but I do use him a considerable amount, although since getting the Edwin Diaz 94 ovr, I'm tending to go to Diaz before considering
using Hoffman. That Diaz card... He throws fire, and he's a strikeout machine. Not that you need him considering the Pen you posted, but if you really hate using Hoffman, give Diaz a look. I got him in one of the flashback packs that you earn working your way to the SS Vlad Guerrero. I've only gotten 2 good cards from those packs (3 packs for every player leading up to the Vlad SS card)
