The counter argument is how good is it going expensive? Especially on starting pitching?
Price and Sale cost the Sox about $305, if you only look at Sale’s extension and remove COVID money plus money paid by LA and Atlanta. And for that $305mill, the Sox received a grand total of 12.3 bWAR. For 8 seasons of pitching, they got roughly twice what Sale gave Atlanta last year.
Nate Eovaldi signed a 4 year $68mill contract, which became a 3.4 year $57mill deal. Eovaldi gave Boston 7 bWAR in 3.4 seasons, making him, by averaging just over 2 bWAR per year, the best starting pitcher free agent in team history
The Sox dont have many long term free agent pitcher contracts in their history. Since Duquette extended Pedro, they’re sparse. After Price and Sale, the only other one that leaps to mind is John Lackey. Now as Lackey had a great postseason in 2013, he’s remembered as a success, and not as a pitcher who was mediocre his first year, horrible in his second, and didn’t even pitch in his third. Lackey was worth a total of 3.9 bWAR for his 4 and a half seasons in Boston, all for the (definitely not at the time) low, low price of roughly $80million
(And Lackey was also the subject of an urban legend regarding threatening to retire instead of playing his contractually obligated minimum wage year; he did earn minimum wage in St. Louis in 2015.)
Not so sure spending heavy on Fried/Burnes/whoever does anything more than keeping fans from calling the FO cheap…
