You are certainly entitled to your opinion. I think its wrong, but appreciate the point. Nobody in the SBC can rival SBTS right now. Not in terms of academic faculty, facilities, leadership, or (as I understand it) endowment. These things matter.
Sailhammer is a fine scholar and his leaving was difficult. The larger concern at SEBTS is the leadership isn't nearly as scholarly as SBTS. (Let's not get into a nasty bout of name calling...which I'll do my best not to do.)
This is a good link and I'm thankful you provided it. But I think the research is specious. How many of SEBTS' faculty (minus Kostenberger) are publishing outside B&H? How many are considered significant in the larger academic/theological conversation? I don't know of many...maybe Black. Having B&H in your back pocket helps with all this data imho.
I think another thing is (having been to all the seminaries) SBTS is just miles beyond SEBTS in terms of facilities too. While SWBTS has a better library (and honestly better access to more/other institutions because of DFW) it hasn't utilized it as it should. There are lots of questions about SWBTS' perceived fundamentalism in the academic world. I don't know of too many serious scholars looking to the faculty at SEBTS or SWBTS for insight.
Perhaps we can reasonably say the SBTS is the leading school in SBC world right now. My contention about SEBTS and SWBTS essentially puts SEBTS in the lead there (quite a horse race.) If I had to recommend a SBC seminary right now it would (probably) be between SBTS and SEBTS. I loved being able to interact with faculty and have access to so many different church models in DFW...but I think DTS offers a better institution in that region right now.
In the end I think it still comes down to preference in some areas. This is a good conversation...thanks for the insightful post and I certainly appreciate the commitment to your alma mater.
