Huh? Players should want to get paid up front. Compound interest + the value of a dollar will decrease over time.
IF the Jays were interested, I'd certainly think they'd look at front ending the deal. Give him big bucks while all their young stars are making peanuts, then taper it back when they'll need payroll space to pay their young guys. That would create flexibility later in the deal (reduced risk for the Jay) and it should also be a selling feature for Machado. The issue these days is the opt out's....but again, you think front ending the deal, while including an opt out would really benefit Machado.
That said - we aren't signing him - even though it does appear to be a good fit in terms of position and our timeline.
