That might not make him a great clubhouse guy/mentor but it clearly makes him an idol to many. That alone makes his words much more impactful by comparison.
Also, I haven't follow Pujols like TMZ but there would be many stories out there of him as a locker room cancer despite his talent. Players like to learn from someone who has been there and done that so what better person fits that criteria?
I'm not even saying the Jays must go out there and sign him. Taking up a valuable roster spot should mean you provide more to the team than just these intangible skills. Denying that these intangible skills dont exist seems foolish though.
