The contracts are no doubt risky, but signing Bellinger, Chapman and JD Martinez is probably the absolute best the Jays could do as far as FA's go. Probably the most formidable line up they could put together at the moment without doing it via trades.
LF - Springer
SS - Bichette
1B - Guerrero
RF - Bellinger
DH - Martinez
3B - Chapman
C - Kirk / Jansen
2B - Biggio/ Schneider / Espinal
CF - Varsho
One more for the bench out of Lukes, Clement, Horwitz, etc
Probably not much money left after that to sign anything more than maybe some depth pitching, but the staff is pretty solid on paper as is.
