I think you have it backwards. Cael is on record saying Nick was making more out of the injury than warranted. That doesn't sound like a coach pushing for surgery.
Listen again. Nick says repeatedly he's glad he didn't have the surgery. And i guess the Big10 must have agreed with Suriano's assertions that he was being coerced into having unwanted surgery, otherwise , why give him an immediate waiver. Unless the Big 10 just did not want to open a big can of worms. Which now sounds likely.
