Again, it’s a risky hire for a reason. I don’t think any coach has this key to unlock the skills of 3-4 star players over and over again to the point that you’re a championship program. One here, one there, but just because he’s such a good recruiter of talent, not sure I would hold development against him.
Why don’t you believe he’d be able to recruit 4-5 stars to Penn State? Did you read the article? Ohio State had no 5 star recruits at the position the preceding half decade before he arrived. Have had numerous since. I think he’d recruit the position very well.
There is a candidate with evidence of 3-4 star development, and I’d be even happier to get him than Hartline. Joe Brady was Co-OC at LSU when they had Chase and Jefferson. Both clearly unicorn NFL talents, neither 5 star recruits.
