The long term success as I already stated, is the success that PSU fans are expecting. We all know what has actually happened, and are here discussing how to possibly right the ship.
Regarding portal QB's, competent QB's don't go from the portal to be backups to 3 year starting QB's with other QB's on the roster that likely had higher ratings than the portal QB and that have already been in the new team's system for a year or more. If Fields was available in the Spring of 2021 I'm not sure he would be a candidate to come to PSU with Clifford entrenched. Fits for portal QB's, especially at PSU where Franklin has shown loyalty to seniors and returning starter, are hard to find and hard to predict.
And I don't believe Franklin has "whiffed" on QB recruiting. Franklin recruited McSorely and Fields and got commitments from both of them. Way before other QB evaluators, of which there were numerous, bought into either of them. That right there dispels the "whiff" comment. But Franklin also recruited Clifford to PSU and Clifford was good enough to win 11 games in 2019. So if you want a QB with more success than Clifford to transfer to PSU you are kidding yourself. Veilleux may also prove to be an above average or very good B10 starting QB if he ends up starting games. And right now there are two highly sought after QB's that just enrolled, one of whom was rated the #1 QB coming out of high school Whiff?? Hardly.
And the Iowa debacle was not as straightforward as you make it, as Roberson may have done better had the crowd not been so obnoxious. And Veilleux looked pretty good later in the season, so it might be that there was a competent backup QB (or 2) traveling to Iowa in 2021. One bad game for Roberson does not mean he is without talent, and if the same thing happened later in the season for all we know Veilleux might have been the backup at that time and came in and been more than good enough to hold the lead against a team like Iowa, who I believe PSU was 2 TD's better than on most any day. It also may have turned out better against Iowa had Franklin and his staff got Roberson (and or Veilleux) more snaps in a couple of the games prior to Iowa, and hopefully Franklin and Yurcich will do that going forward.
The plug and play model for college QB that you seem to believe in does not exist. For every one portal transfer that makes a splash there are more than one that also strikes out at their new team. Not much better than the results for recruiting high school players. The only advantage for the teams that do recruit high school player well, and that includes Franklin's PSU, is the ability to TRY and plug a hole at a position of need. And for every Ebikitie and Tangelo there will be Wilson's and Lovett's and Lytton's that did not do much or anything to solve the position weaknesses they were brought in to solve or compliment.
Franklin has adapted. But if you are expecting an inflow of transfers like MSU is doing you will be disappointed. And I'm happy that Franklin is a better recruiter of high school talent than what the last 2 MSU coaches are because Franklin will not have to rely on the crapshoot of the Transfer Portal the way the MSU coaches have. Franklin, if he can keep bringing in top 10 recruiting classes, is more likely to emulate teams like Clemson who reload from the players on their roster as well as the highly talented freshmen they bring in. Clemson has just brought in their first transfer portal player, Hunter Johnson, who enrolled at Clemson out of high school, transferred to Northwestern because he was buried on the Clemson depth chart, and then recently transferred back to Clemson after the grass was not greener at Northwestern.
