First, slow your roll with the stupid talk. Even the intellectual elite like yourself must know there are differences of opinion within one "fan based." Further, there is a difference between blasting an AD whose definition of a "nationwide" search lasts all of 10 hours before stroking a check for a $4mm buyout for a guy that was on the payroll about 2-3 weeks prior, and blasting a HC for failing to make an OC hire before the end of the dead period when there are all of 4 recruits on that side of the ball.
Second, take your cape off, open up your eyes, and understand the clown show aspects. Do you think Manny doesn't know who he'd prefer yet, and that's why there's this delay? You think he and the other coaches and Blake are making spreadsheets and comparing advanced metrics to determine which available coach is the best fit possible at UM? If you do, I have some beachfront property in Utah I think you may be interested in. The reality is Manny announced the morning of 1/2/2019 (a week ago) that he has his list of preferred candidates (3, with an "amazing" 4th). If he had his list of 3 (or 4) on 1/2/2019, why would it take more than a week to gauge interest, bring those guys in for an interview, and make a hire? In all likelihood, he's either waffling on the choice (clown show), getting rejected and looking at different options (clown show), fighting with the BOT/AD about the hire because there is internal disagreement about the choice (clown show), or there are salary issues/we're getting played for raises/jobs by the candidates because there names leaked too soon (clown show). Clown show, however you slice it.
Third, I would expect a scholar like you to recognize Manny Diaz, a brand new HC, is a former DC. He is known by recruits as a DC. His expertise is defense, and he has never been a HC. So while I have no doubt Manny has made calls on the offensive side of the ball because he is a passionate guy who wants to succeed, how meaningful do you believe those calls are to recruits on the offensive side of the football? Also, you may recall from your time as the wisest Hurricane's fan of all that Coach Diaz has never been considered a strong recruiter.
Fourth, while it's only been 11 days since Manny was hired as HC and he has made 1 hire (on the defensive side of the ball), he has had more time than that to consider his options. He was hired over two weeks prior to being hired here for the same position at Temple. Although I recognize the quality and type of candidate for a Temple OC and assistant coach hires is different than what I would expect at UM, one would think he'd already been looking around at who is available, who fits the style of offense he would ultimately like to pair with his defense, and what coaches on that side of the ball he would like to work with. So it isn't like he suddenly became a HC on 12/30 without strongly considering his hires. He has had considerably more time to think about these issues (which likely explain why he had a list of top 3/4 candidates within 3 days).
