Last season there were a lot of holes to be filled due to NFL departures and obvious deficiencies.  I am going to get roasted for this, but I don't see that this year.
The D is stacked with a lot of upperclassmen.  Would we take a great portal addition?  Sure, especially at CB.  But, with what we have and what is behind them, the D is just fine.
On offense, there is a combination of three factors that will make finding any quality portal candidates kind of tough.  First, we have a lot of returning starters.  Granted, the quality of those starters is questionable, but I don't see KF running too many folks off, so who wants to come into a new program and try to beat out an established starter?  Second, the offense was so sucky for so long, who besides a TE candidate would want to enter that swamp?  Third, to get anyone really good, I suspect will cost some serious NIL money and I don't know what is there for a good OL or WR or back-up QB.
There will be some portal activity at some point, but I would not hold you breath for anything close to what happened last year.
