re: How is this the fault of Alleva?

In summary:

First, Wade wasn't being investigated. This was an investigation into Christian Dawkins.

As for as why this is Alleva's fault. Well, it might not be all his fault because King is the one who told Alleva to suspend Wade, but it was a knee jerk reaction.

For whatever reason yahoo published their article the day after we beat Florida on the road (which put us undefeated on the road in conference play). Will Wade wasn't the only coach the feds had information on, discussing "pay for play".

They had text from Bill Self (Kansas HC) discussing offering Zion Williamson $100k & a new house for his parents. A year earlier a report was published about the whole FBI investigation and it said that there could be up to 50 schools involved.

Alleva knew about the whole FBI thing and Will Wade being part of the investigation since at least October, which he made a public statement about.

So why all of a sudden suspend Wade, especially with the success the team had and right before the NCAA tournament? Even if there was anything, suspending him wouldn't change anything if they were going to vacate the wins, the SEC title, etc. The damage would have already been done.
