As crazy as it may sound, yes, absolutely it'd have been a good signing.
To put it in context, Rogers spent $5.2 billion for NHL rights that they've taken an absolute bath on. Ohtani would have cost 20% of that amount and would have made the Rogers enterprise hundreds of millions of dollars over that same amount of time (12 years).
In the aftermath (and heartbreak), Ohtani was essentially a unicorn. This was a once-in-a-lifetime opportunity. Not just getting the player. All that Ohtani would bring is something we have never seen or experienced before, and likely never will.
As disappointing as it is, I can't fault Rogers and Shatkins much, if at all, for this. Many said all season he'd end up with the Dodgers. He did. The team (based on all the reports) offered at least half a billion dollars. That's a lot of coin to commit to an offer. The excitement for that short window of time when it was made he'd be a Jay was some of the most heightened excitement we've ever seen -- even non-Jays fans were buying in.
What sucks now is that the rest of the off-season will consist of, "Well, it's not Ohtani.". It's going to be a letdown whatever happens at this point. But a job has to be done, and hopefully management has been stoking other fires while the Ohtani hoopla was going on. This is still a good team, but has a lot of holes to fill.
