Your suggestion was a very, very, very large overpay. I'll use BTV for current players and fangraphs FV value estimates for prospects.
Made - 60 FV prospect so $55M value, Pena - 55 FV prospect so $46M value, Pratt - 50 FV prospect so $28M value
Ortiz - $16.7M value
Henderson - 50 FV prospect so $21M value
Letson - 45+ FV prospect $6M value
for
Abrams - $50.1M value
That's a roughly $49M overpay with Made, $40M overpay with Pena, and $22M overpay with Pratt.
