For a while, UM was still putting players into the NFL, and they stuck around. Perryman, Burns, Feliciano, Duke, Jaquan, Berrios, Osborne, Njoku. That stopped around 6-7 years ago. The team has been stuck in 1st gear. When the talent was around, the coaching misused it. That caused talented recruits, the difference makers mentioned in another post, to choose other programs. Mario has started to bring talent back to Miami, but that won't last if the team continues struggling to reach 7-5.
The problems at QB illustrate the problem. The top QB recruits aren't interested in an anemic offense scheme and you can see that in the incoming 2024 class. Judd Anderson is UM's 3-star commit at QB. Except for Mississippi, the other programs that showed interest in him were at the same level as UM. So, Mario might bring in top OL, DL, LB, DB and receiving talent, at least in the short term. But without a dynamic offense and a NFL-quality QB that can keep up with the competition, Mario will find it difficult to bring talent in, fans will call for a change, and the whole cycle starts over.
The cycle might have cracked a bit with a knee and a 4-and-1 conversion to put the team at 8-2 right now. Heck, 27-20 against FSU is even better than many would have predicted. But, alas, the team is 6-4 and possibly on track for a 6-6 season and another meaningless bowl. The cycle continues.
