It's a grey area. A better team would mean better teammates, but depending on the player it could mean less ice time as well. If it were Crosby or Ovechkin, they'd get 1st line time regardless and would reap the benefits of better teammates. For a kid like Hall, who's not an established 1st liner, less time would factor in as well. Then it also depends on the team. Is Hall getting less time on the 2nd or 3rd line, or is he with 4th liners? Depends on how good the team is. If it's a middle of the pack team and he ends up with decent time, I'd say it's a positive, but if it's a very good team and he ends up on the 4th line, it's a negative.
