Two things can be true at the same time.
Yes, Kenny Baker does not have a deep resume. One could look at this track record and say he does not have enough skins on the wall to be coaching DTs at Texas. His ability to recruit is unproven. All of these are red flags.
However, Texas under Sark has shown no reluctance to spend money to get top coaches. They were willing to break the bank for Bo Davis, but dude likes to move around and had family reasons to go to LSU. Texas just went and got Arizona's DC to be its linebackers coach. Sark presumably had plenty of cash to chase a wide range of options for a DL coach. He ended up with Kenny Baker. It seems likely that since this process was not rushed, and Texas had resources, that this was a hire Sark wanted to make. So in his view Baker is a plus for the team.
Given his track record in hiring coaches, and Baker's experience in the deep south, it seems prudent to give Sark some leeway and see how Baker works out. Maybe it's a tragic mistake. Or maybe it's the beginning of a beautiful friendship. Like CTJ said above, the hire is singularly great because it was so out of the blue it is going trigger a lot of debate among the populace of this message board. We get to enjoy seeing morons be morons. A few years from now we'll be able to look back at some people and laugh.
Truth is, we don't know shit about fuck when it comes to how this will all play out. Embrace the chaos.
