First, if you don’t read Matthew’s blog, you should. When he does write over there (yes, that’s an open poke at Matthew to get him to write there more) it’s always excellent with great insight, especially since he’s living and breathing Cardinals on a daily basis.
Second, Matthew sums up my thoughts on the Miles saga perfectly. In short, it’s not about whether you think he’s a superstar or not, it’s not about whether you think he’s a plus or minus fielder, it’s about whether he can be expected to reproduce his career year from 2008. At the salary he will receive, it’s a gamble on Miles actually earning it.
The Cardinals are not (and I agree) willing to bet on Miles at that price. The opportunity cost is just too high.
