JFC, will this please stop? The bolded was not done for, nor was it related to, the recruitment of Dylan. Donovan was the only assistant whose contract is set to expire after this past season since he was retained on his original contract that had 1 year left. Donovan is clearly doing a good job and Rhule likes him a lot and wanted to keep him, thus an extension and a raise to recognize the good job he has done this year.
—edit—
It has also been reported that Donovan’s extension was done a few weeks ago, before Dylan came back into the picture.
