The Red Sox seem to go in cycles. They still have a lot of home grown players, and in that way the 2018 team was similar to the Yankees of the late 1990s. Their homegrown players provided a strong core and they hadn't gotten expensive yet. But they always seem to eventually succumb to the temptation to buy their way into greatness, and they have been saddled with bad contracts (Price and Sale, for example). The Yankees of the early 2000s stopped winning once they started bringing in the guys with the huge contracts (Giambi, Mussina, A-Rod, etc.).
zambonir, what do you mean buy the kids will have to move? Are you thinking that a Boston GM won't last? Aside from Theo's 9 year tenure, that has been true, but a GM coming in would have to feel that he would not be able to succeed long term if they went in thinking they wouldn't last in their job.
