Jeff Hecklinski apparently will coach wide receivers and currently is co-recruiting coordinator at Michigan with Chris Singletary, who handled that position for Rodriguez the last three seasons.
Seemingly a smart move to retain him. He's not a "coach." But he's a link to what's left of the recruiting class. I'm sure that, as a "co-," he's aware his time is limited. But I'm sure RR is taking the year off, anyway. They'll be back next year, but (apparently) not alongside many of the familiar faces/hairstyles.
