Tim's defense has been very suspect at SS. At some point, he may need to be moved to the OF. He has the tools to be an elite outfielder, especially in the corners (with Robert already being the CFer, obviously). He wouldn't need to hit like a beast to be valuable out there. It would be similar to Alex Gordon moving to the corner OF and being elite out there. It is safe to say that Tim is a better hitter than Heyward, and likely a lesser defensive corner OFer than Heyward. Heyward still contributed to a WS team.
Could he be our Alex Gordon or Jason Heyward? Elite in the corner OF, with a passable and possibly above average bat out there. Having Tim and Luis patrolling the OF would be exciting. The Sox would need to find a new SS if that happened, of course. A certain Francisco Lindor is a FA after 2021...
