I do too, but maybe not for this season.
One problem with having 6-8 guys fighting for the 5th slot rather than having 5-6 solid starters to begin with is that the trial and error aspect trying to find that one guy who sticks may take months and too many losses to be able to withstand.
I started a thread on "that other site" titled "Too much Quantity and not Enough Quality" that addressed this concern. It kind of ties into my philosophy that it is hard to significantly improve a pitching staff by trying to acquire a "better" 5th starter than the one already in place. I know it's easier said than done, but it's better to try to acquire a solid 1-3 starter or a top #4 type starter and then move your current 4 to the 5 slot.
For informational purposes, I'll provide a brief history of our rotation since 2003 (GS).
2003: Lowe & Wake (33), Burkett (30), Pedro (29) then we had Fossum, Kim and Mendoza fighting for the 5th slot before trading for Jeff Suppan. We even ended up trying Bruce Chen (2) and Ryan Rupe (1).
2004: We had a solid 5 with no injuries- Pedro & Lowe (33), Schilling (32), Wakefield (30) and Arroyo (29). We had Kim (3) and used Pedro Astacio(1) and (Abe Alvarez (1)
2005: We basically replaced Pedro and Lowe with Clement (32) , David Wells (30) and Wade Miller (16). Wake had 33, Arroyo had 32, and Schilling 11 starts. We also saw scattered starts from Geremi Gonzalez (3), Papelbon (3), Halama (1) and DiNardo (1). I'd say this season we had 5-6 solid starters, but none ended up with an ERA below 4.15.
2006: Was a mess. We did have some quality starters 5-6 deep, but some injuries derailed us. Beckett 33, Schilling 31, Wake 23, Clement 12, Wells 8. The replacements were better than we have now: Lester 15, Snyder 10, Tavarez 6, DiNardo 6, Jason Johnson 6, Kason Gabbard 4 then 3 from K Jarvis & D Pauley and 2 from Devern Hansack.
2007: A major similarity to 2004 was the fac t that our top starters pitched a lot of starts: DiceK 32, Wake 31, Beckett 30, Schilling 24 & Tavarez 11. With Tavarez, Lester (11) and Gabbard (7) sharing 5 slot duties, we were again much better off than 2016. Buchholz got 3 starts and Hansack 1.
2008: Our top 4 were solid- Lester 33, Wake 30, DiceK 29 and Beckett 27. On paper our #5 and down slots had some nice pitchers (Buch 15, Masterson 9 and B Colon 7), but we ended up having to acquire and use Paul Byrd for 8 key starts. Others used were Pauley 2, Bowden 1 and Zink 1.
2009: The experiment of signing Brad Penny (24) and John Smoltz (8) was a total failure, but I can see how management would prefer that plan to a round robin attempt at finding a kid in the system that will produce. I ahted the plan from the start. Other starters that year were Beckett 32, Lester 32, Wake 21, Buch 16, Dice-K 12, Masterson 6, Byrd 6, Tazawa 4 and Bowden 1. I'd still give the nod to these 5th starters and below than today's.
2010: Had a nice 6: Lackey 33, Lester 32, Buch 28, DiceK 25, Beckett 21, Wake 19 with Doubront getting 3 and Atchison forced to get 1.
2011: We started to get a little shaky after the 5 slot and ended up trading for Erik Bedard's 8 starts. Lester 31, Beckett 30, Lackey 28 (playing hurt), Wake 23, Buch 14, A. Miller 12 and Dice-K 7. Weiland got 5 and Aceves 4
2012: The shaky trend continued after the top 3 Lester 33, Buch 29 and Beckett 21 with Dubront getting 29, Aaron Cook (PLEASE!) 18, Dice 11, Bard 10, Morales 9 and Zach Stewart 2.
2013: The signing of Dempster was a severe overpay to add stability to the bottom of the rotation. Some say it worked, since we won a ring. Some say the trade for Peavy was a key to winning the ring. Buch's injury forced our hand somewhat, but here's the numbers: Lester 33, Lackey 29, Dempster 29, Doubront 27, Buch 16, Peavy 10. We also used Webster 7 (8.60 ERA), Aceves 6 (4.86), Workman 3 and Morales & Wright for 1 each.
2014: Back to being messy, but on paper we had a solid 5 to start the season-- Buch 28 (the ironman!), Lester 21 (traded) , Lackey 21 (traded), Peavy 20 (traded), RDLR 18, Workman 15, Webster 11, Kelly 10, Doubront 10, Ranaudo 7 aqnd Wright 1.
2015: Surely a rotation lacking top quality at the top: Porcello 28, Buch 18 and Miley 32. After the top 3 starters, we used Kelly 25, ERod 21, Owens 11, Wright 9, Masterson 9, R Hill 4, Breslow 2, Barnes 2 and Johnson 1.
Our 2016 rotation might have been a lot better so far had ERod not gotten hurt. I liked our top 3 on paper: Price, ERod & Porcello. I felt pretty confident that Kelly or Buch would be a solid #4 and perhaps give us a solid #5 as well, but I didn't expect it to be this bad. I've always liked Wright, but never thought we'd need to value him as our #2 guy. Owens and O'Sullivan failed. I suppose Elias will eventually get a look. I doubt Johnson does at this point.
My guess is we look outside the system in July.
