Not source wise. But a few reasons.
1) Hamilton/Cheek want to rally the fanbase. If they think they have their coach, they will do whatever they can to get it done fast. With a big name like Lawrence Frank, this will help stabilize the fanbase.
2) Recruiting. We got Ware on board already. It seems something is going on, and McRae is confident we are going to get a good coach. The quicker you hire a coach, the quicker you can recruit. We still are in on some talented prospects.
3) Going into Final Four, you can be the talk of the media. Everybody saying what a proven commodity you have, people talking about Frank as an X's and O's genius, and how his NBA connections will help recruit. We can cast Tennessee in a positive light.
4) It helps move the program past Bruce Pearl. We can now focus on the future, and move on from the past. If it takes, let's say, a month, then that's more time people focus and worry about how we should have kept Pearl. We can now get ready for the new chapter in UT basketball.
