Hawaii is expected to announce Greg McMackin as the successor to June Jones at a news conference on Wednesday, two sources familiar with the situation said Monday. An official announcement will not come until Wednesday, at the earliest. Barring anything "highly unusual" occurring between today and Wednesday, as one source stated, McMackin will be named coach. McMackin is Hawaii's defensive coordinator and was endorsed on Sunday by Jones for the position. McMackin could have joined Jones as SMU's defensive coordinator.
