You can talk about whatever you want within the rules of the message board. It would be wise however to wait for final confirmation of the contract details before picking it apart. For all we know right now, there is a reasonable buyout on year 6, or something like that.
In general, I don't think any Blue Jays fan should worry much about a big contract like this. To say that fans should not care about the money because it is not their money is a trite point... fans should care when the deal could reasonably hurt the organization in the future by limiting their ability to retain players, sign new players, and stay competitive. There are many examples of bad contracts severely restricting baseball organizations.
But here, the Blue Jays are wonderfully positioned to take the risks involved with these big silly contracts - they have little in guaranteed payroll commitments over the next few years and you have to squint uncomfortably hard to imagine a future where one $25M contract in 2025/2026 will prevent the team from doing anything meaningful. The Blue Jays should carry high payrolls given their ownership structure and market.
And even if the Springer contract does go bad and Toronto does not get their money worth, the plain fact that Rogers was willing to write this cheque should be an exciting thing for Blue Jays fans going forward. It's a signal (along with Ryu last year) that the team is ready to cement its place as a big player (likely in the second tier of teams, behind the really big spenders).
That's all to say - to immediately hone in on year 6 and discuss how the contract is an overpay by about one Tanner Roark is just kind of sad right now. Like, a depressing way to see the world, man.
