Manager rep was totally useless for us, when we took our supposed "Worldclass" rep, and went back to the LIHL, with a new team.
We were unable to even talk to any free-agent player above lvl 67.
Only about half of the lvl 65 players would even talk to us.
About 66% of the lvl 64's would allow us to negotiate a contract with them.
Once the team won a few games: a few more players were listening.
There seems to be a definite change with the team rep, but manager rep was zilch.
I think team rep counts more for signing FAs
