I have read many think he has Ace upside as a pitcher. Expectations vary as a hitter but I have seen some puttimg his ceiling as a 30/30 right fielder.
Apparently he wants to play in the field so a team willimg to let him try might have a leg up.
Olney has said recently that the Jays do not plan to pursue him heavily. That being said, they had 8 or 10 front office personelle over there scouting him and apparently Dan Evans has been working on him for years and badly wants him. There have been many reports on how players love playing for the Jays passionate fanbase and representing the whole country. Maybe that (and taking over some joey bays endorsement deals) could be enough to sway him. He clearly is not all about the money.
