My observations by position:
CB
Likely the most talented position on the roster with Dixon, Tracey and Collins as returning starters and Joseph a talented young player that has some experience.
Also a position with youth, with Dixon as a Soph, Joseph, Johnson and Thomas also from the 2025 class (and Sowell from the 2025 ISU class), and 2 true freshmen in Chatman and Zayas.
Safety
The 3 ISU transfers, all upper classmen, and Toure seem to be the leaders to form the 2 deep, but there 2 younger transfers from BC and Syracuse will also be competing to see playing time, likely on special teams as well. Two true freshmen to develop.
DE
Talented but young likely starters in Granville and Kemajou, but a lot of unknowns at this point behind those two. Holdovers that haven't done much on the field in Robinson, Mayers, and the RS freshman Burnett as well as Arrington who reportedly is athletic but looks light for DE at this point. Wonder if Arrington will be bigger than his current listing by the Fall. DE seems to need the incoming experienced transfers to be ready for significant roles, Ezeogu and McPherson. Maybe the true freshman Ford gets to play as he seems to have the size to contribute. It seems a good many of the DE's are pretty light as well with a number of them 240 lbs or lighter.
DT
Blanding played more as last season went along and seemed to play pretty well and should team with the incoming upper classman transfers (Taupaki, Vacalahi, and Williams all over 310 lbs) to form a pretty stout group with more size than last season's DT's. Also a good group of DT's as candidates to break out as contributors including Cook, Nnodim, Carnell, Andrews and Brewer who moved over from OL.
DT should be a big focus for the 2027 class as there are no true freshmen on the roster.
LB
Rojas and the young 2025 PSU class LB's Tatsch and Smith will compete with the 4 ISU transfers (all 230+ lbs) that are all upper classmen. I look for Rojas and the ISU transfers to form the starters with Tatsch and Smith continuing to develop as potential 2027 starters. A position in need of significant 2027 class talent.
QB
Becht is the obvious starter, with Barry brought in to be the likely backup. Staff has a year to develop the young QB's Manske, Falzone, and Evans to compete to start in 2027. Hope the true freshman Falzone is ready to get some snaps in the B/W game as it will be intersting to see him and he's tall and reportedly a plus athlete that can run.
RB
Hanson, Peoples and Martin form a talented group with Martin now listed at 205 lbs with Campbell having challenged him to fill out his big frame.
WR
Sowell, Eskildson and Howard as likely starters with young players with size competing for playing time in Samuel(6'4"), Brookins(6'5"), Gonzalez(6'2") and Jones(6'4").
TE
Loaded. Rappleyea is an all B10 TE, and the ISU transfers Brahmer and Burkle should make a talented depth chart.
OL
Seems to be a talented and stout group with nice depth. Returning OT starter Donkoh with front runners Cousins and Buhr at Guard, Rulli/Riker at Center, and a nice group competing for the 2nd OT spot in Goodman, Aliciene and Sexton. Pretty mature and good sized depth inside from Onoh (6'5" 321 who may compete at OT as well) and Ikakoula (ISU transfer). Harbour hasn't really competed for playing time his first 2 years at PSU after being a highly rated Guard recruit from Wisconsin but is now listed at 6'3", 325 lbs and may be ready to get onto the field as well.
Roster looks pretty well stocked but Campbell really needs a talented 2027 class to get more young talent on the roster.
