I have no doubt that he's "on the market", but I struggle to find a team hypothetically willing to overpay for him.
I also look at his value to Rogers off the field and even knowing he's underperformed his 2021 ceiling ever since he's unquestionably the face of the Jays and the face of the Rogers marketing machine to the casual fans. And, like it or not, that's a huge factor in his tradeability.
Purely from an on field only perspective, of course he's tradeable, every player is. Nobody is untouchable when you look at only the on field part. It's the off-field part that makes it murky with Vlad.
I'm not saying its right, or wrong, it's reality. Trading Vlad, regardless of him being the biggest trade chip, is far more impactful than just the on-field product.
All of that said, name me the teams you suspect would be willing to overpay and I'll gladly entertain that discourse.
