it was inspired by the statues at the entrance to the Hope Memorial bridge near the park that are called the "Guardians of Traffic".
Besides Spiders, Rockers would have been a good choice given the RnR HoF. A local radio station ran a poll a few months ago, Spiders and Rockers were #1 & 2, with Guardians finishing 3rd.
I liked the Rockers too. Plus they could have played "Cleveland Rocks" on their scoreboard during every game.
