In theory that is a good point, but there is hole or two in your analysis. Chuck James had pitched pretty well for the Braves through July, 2007, posting an ERA of about 3.7 in 22 starts through that point. In fact he had a very good July. However, in early August he was obviously injured, making only three starts for that month with an ERA of over 8, before missing the last two weeks of the month. He did come back in September and was so-so in 5 starts. HIs WAR of the season was 1.8, and was probably at a 2.0 or so, through July. So I guess had the Braves been clairvoyant and seen that he would go into the tank immediately after the Tex trade, I guess you have a point. The other two starters were pretty much ineffective in August and Septemebr, although Buddy Carlyle was semi-decent, and better certainly than Jo-Jo.
Was there a pitcher or two on the market who were available and who would have given us the net 3.0 WAR bump that Teixeira gave us over the last two months of 2007? I'm not sure of that. We did trade Kyle Davies and his 6+ERA and -0.9 WAR to the Royals for Octavio Dotel the same day as the Tex trade to shore up the staff, although Dotel gave us mixed results.
I loved Chuck James back in the day as someone who found him amusing and loved that he got results in the minors. Vut he was smoke and mirrors. His first half ERA was solid, but his FIP clearly painted the picture of a guy who was getting lucky (first half FIP of 5.08) Second half numbers produced the same basic K rate better BB rate and insane homer rate.
As far as starters rumored on the bloc. Jon Garland, Javy Vazquez (with Jermaine Dye if you want to add offense)
No one pitcher would have been better for us than teixeira, though who knows
Some guys traded in the 07 offseason who may have been available include Garza and Haren who may have been had for what we dangled for Tex (never would know)
Bottom line is that we didn't win the division, we traded the whole farm to address one need as well. Teixeira playing the best 2 months of baseball he played has little to do with what the trade sucked so hard. It was clear to most that we needed pitching. We had 2 stars, one of them super old. After that some 4s 5s or worse.
So to answer your Rex question probably not one but maybe we throw Salty to Chicago with some other stuff and get Javy and Garland. And who knows how things shake out from there. What I do know is we had 35 srarts from Buddy Carlyle, Jo Jo Reyes and Mark Redmond, all known turds. James crushed his peripherals to have a modest ERA, Davies was shot (to my dismay) from his injuries. Our closer was Bob Wickman, we had 2 of our most used relievers as Tyler Yates and Oscar Villarreal. If you build a BP of our 7 most used relievers you get (with ERA)
Wickman - 3.92
Moylan - 1.80
Villarreal - 4.24
Raffy - 3.00
Yates 5.18
In the end the terrible trade of that year was trading LaRoche.Would have been a slightly worse team in 2007 with him and without Tex, Mahay and Gonzalez, but it would have kept the farm in tact and we could have made different adjustments. Like imagine we trade for Dan Haren.
We were not gonna win games throwing out Jo-Jo Reyes and Buddy Carlyle, they're total bums. What team wins with bums like them?
