To be fair and shoot him some bail it’s not uncommon for big targets of teams to get the best recruiters on staff and not the position coach as a primary. It happens
Here's the thing, you tend to be one of the more honest and fair people in your assessment of Rumph.
On the other hand, we have guys who just DESTROY Rumph. Guys who yap about where Rumph's guys are drafted (without noting that Rumph's recruiting and draft-outcome of his players is comparable to UM's overall). Rumph started coaching at UM in 2016.
Rumph's recruiting and talent in the passing defense:
2016 - UM's recruiting was not good (just got Rivals/247 4-star S Romeo Finley)
2017 - got a bit better (Rivals/247 4-star CB Trajan Bandy and 4-star transfer CB Jhavonte Dean)
2018 - was a lot better (Rivals/247 4-stars CB Frierson, S Hall, and CB Blades, and 247 4-star CB Ivey)
2019 - had lower numbers but we got a couple (Rivals/247 4-stars CB Williams & S Smith and 247 4-star CB Couch)
2020 - was great for quality and quantity (Rivals/247 4-stars S Harrell, CB Dunson, and S Williams and Rivals 4-star S Washington).
I realize those names include safeties, but there is some overlap, and if a coach was such a poisonous person and recruiter (see, generally, Greg Knox at UiF), you would expect to see guys transferring out in greater numbers.
Rumph's coaching:
2016 - #47 ranked passing defense (yards allowed per game) per NCAA
2017 - #56 ranked passing defense (yards allowed per game) per NCAA
2018 - #1 ranked passing defense (yards allowed per game) per NCAA
2019 - #18 ranked passing defense (yards allowed per game) per NCAA
Rumph's NFL draft results:
2017 - 5th round CB Corn Elder (coached by Rumph for 1 year)
2017 - 7th round CB Adrian Colbert (coached by Rumph for 1 year)
2017 - Miami had 9 total draftees: 1 first-rounder (TE Njoku), 1 fourth-rounder (S Jenkins), 2 fifth-rounders, 2 sixth-rounders, 3 seventh-rounders
2018 - no DBs drafted
2018 - Miami had 6 total draftees: 1 third-rounder (DE Thomas), 2 fourth-rounders (TE Herndon, RB Walton), 1 fifth-rounder, 1 sixth-rounder, 1 seventh-rounder
2019 - 5th round CB Mike Jackson (coached by Rumph for 3 years)
2019 - 6th round CB Jaquan Jackson (coached by Rumph for 3 years)
2019 - Miami had 5 total draftees: 1 fourth-rounder (S Redwine), 2 fifth-rounders, and 2 sixth-rounders
2020 - no DBs drafted
2020 - Miami had 4 total draftees: 2 fourth-rounders (LB Quaterman, RB Dallas), 1 fifth-rounder, 1 seventh-rounder
--------4 CBs drafted out of 24 total draftees from 2017-2020 (plus 2 safeties)
I'm not evaluating this on the basis of "Rumph is a Cane" or "Rumph is the devil" biases. Looking purely at the stats and objective evidence, it looks like:
---Rumph is not the greatest recruiter, but the last 2+ years for talent (even if he is not the lead recruiter) have gone better than the first 2 years
---Rumph, as a person, is not disliked by his players (in the form of transfers out) and his reputation has not "run off" all blue-chip kids, though we certainly appear to have lost some 4-star/5-star talent in the first 2 years
---Rumph, as a coach, has produced good statistical results, with the last 2 years being better than the first 2 years
---Rumph, as a developer, has coached 4 drafted CBs (2 Round 5s, a 6, and a 7) during a time when Miami has had 24 players drafted; and of the 24 players drafted, only 8 went in rounds above all the CBs (Rounds 1-4) and 2 of those were safeties (and 2 were TEs and 2 were RBs)
---Rumph, overall, when recruiting, coaching, and developing the passing defense, is producing better results than QB, OL, WR, DL, LB, and K/P position groups, and is on a par with RB and TE position groups.
But, hey, even in the face of all of that objective data, we are still going to have people screaming to "Fire Rumph" and telling us about all those CBs that we missed out on 4 years ago.
Oh, and let's not pretend like all these safeties are coming to UM to be position-coached by Banda.
