2. Tableau is a BI software, it's more on the visual end than the back end. I have exposure to Tableau and can use it at work, but I don't have personal access to Tableau or SAS for personal use. Just too expensive. R is open source, Excel comes with any MS Office program commonly installed on most PCs, and SQL Server Studio 2012 is also free for personal use. If I had $10K to spend on software I might consider those you mentioned for personal use, but again, I probably wouldn't. To relate it to this article, AJ is like the old open source software I use. Gets the same results, cheaper. Salty is the newer sexier option, but you will pay 2-3x what you would pay for.
As mentioned above, Saltalamacchia is a 28-year-old switch-hitting catcher who has hit 55 home run over the last three years with the Red Sox (which explains why this report is coming from a Boston newspaper). His OPS over those 3 years is .763, which would've been second on the Twins last year. Overall, those numbers about match what Ryan Doumit did back in 2012, which is very solid.
