If we get Groh as WR coach, great. He's a top 5 recruiter in the industry and looks like a helluva WR coach to boot. But you absolutely do not hire OC's or DC's that aren't backed up by the HC's own competency in that area merely based on recruiting acumen. Aside from the HC himself, that will always be the most important hire on the roster. And Groh has not shown much at all in the way of being even a good OC. Maybe he will turn out to be one, but there's no reason for us to be the ones taking the risk on him at this juncture.
This is why we've kind of pigeon-holed ourselves with two subpar to abysmal recruiters on O in Watson and Chambers (unless he's taken off the field, as he should have been years ago, giving us an extra coaching slot to work with), a mediocre to good one in Robinson (Bobby Burton gave him a C recruiting grade, although I had heard he was better than that), and a good one (but not a guy used to going after big fish) in Wickline. Now the WR/OC/co-OC guy has to be both a rainmaker and an offensive genius.
RBs are productive largely based on natural instinct and talent, so that position coach is generally an ace recruiter. TE is obviously the least important coach on the team, and thus your rainmaker recruiter (Tim Brewster, Josh Henson at LSU, UT's false perception of Chambers) is often put there.
Kyle Shanahan makes some sense because regardless of his actual recruiting ability, he's played at Texas, knows the Texas landscape, and has a huge allure from being RG3's coach and play-caller at Washington. Lincoln Riley makes some sense as well based on position assignments, but I doubt he's ready to carry the load as a recruiter.
Here's what makes a SHIT TON of sense. Hiring a rainmaker like Groh or retaining Wyatt at WR coach, pushing Chambers out, and hiring Josh Henson (another one of the top recruiters in the country) to OC/TEs. We're particularly hamstrung at OC unless we combine WRs and TEs due to Watson being named QB coach, as most OCs are also the QB's coach. Though if we do combine WRs and TEs, the OC could just focus on the offense entirely and skip around to whatever position he wants.
