I know that Geiger has not been held in high esteem on this board for many years. That said, I don't believe I've ever put him down based on his name/reputation. I have disagreed with his perspective, analysis, point-of-view, etc. at times, and limit my comments to the contents of his articles.
The fundamental problem with his argument is that he's making conclusions in the middle of the process. Players are continuing to enter the portal, and it is expected that many more will do so during or after spring practice. If Cory waited until the summer to write this article, he'd have a stronger argument, as the portal process for this offseason would be nearly completed.
Another issue I have with his argument is that it presumes that guys that entered the portal are ready to step into the starting lineup, or provide effective support as a key backup. Some of those that entered the portal this offseason could challenge for playing time at PSU. But only looking at that part of the equation could cause serious problems for PSU's team. While there are some situations where a good player is simply blocked by a better player ahead of him on the depth chart (e.g., Will Levis last year), many others have a variety of issues that contributed to them not getting more playing time, regardless of their natural talent. PSU is usually aware of a prospect's talent, but they try to do their due diligence before offering guys in the portal. Geiger's argument, if I recall correctly, doesn't seem to acknowledge that.
CJF mentioned in a press conference (either at the Bowl game, or on signing day, I think), that many portal players seem to have their next destination determined before they even enter the portal. It's illegal for another college's staff to contact a player on another team's roster before they enter the portal. It should surprise no one that the NCAA seems to be incapable of enforcing this rule. Even if the rule isn't violated, there are many situations where a player enters the portal and has a previous relationship with an assistant or head coach at another program due to their initial recruitment, or said coach having moved to a different program, and there isn't a lot that PSU, or any other program can do, to land those prospects. But if I recall correctly, Geiger doesn't address that part of the portal process.
I had other issues with Geiger's article, but I'll stop there.
