It would be nice if they did come into the ECHL it would help some of the current teams travel costs. As of right now the closest team that Reading travels to is just over 4 hours away. Binghamton would almost cut that in half. I think travel costs hurt most teams in the lower levels.
This may have been said somewhere else in ECHL world but having a lot of Reading's old rivals (Reading, Toledo, Cincinnati) all in another conference really doesn't do those guys any favors. Reading probably has more history with South and Central division teams at this point since most of the North is relocations or recent expansion teams.
If you could pull Wheeling (at minimum) into the North, it'd probably help Reading a bit.
But, yeah, it'd help to get a couple more teams in the Northeast & Mid Atlantic into the ECHL...but it's probably going to be tough to pull off given AHL's been so established with a lot of these towns.
