TCU had a lot of change in the off-season. From what I’ve read, these are the key losses of offense (starters on 2022 team):
QB Max Duggan
WR Quentin Johnson (probably their best overall player)
WR Darius Davis
WR Taye Barber
RB Kendre Miller
C Alan Ali
LG Steve Avila (2nd team all-American)
RG Wes Harris
As you can see, TCU has to replace almost its entire offense, plus its OC in Garrett Riley, who left for Clemson.
At QB, TCU does have Chandler Morris returning, who, as Buff fans will remember, was the starter in the season opener. He didn’t look good, but Dykes seems comfortable with him.
At WR, they lost almost all of the production and Quentin Johnson was a stud. I believe the Frogs are high on underclassman Jordan Hudson, and they hit the portal hard with Jaylon Robinson (Ole Miss, 88 transfer rating), John Paul Richardson (Ok State, 89 transfer rating), and the diminutive Jojo Earle (Alabama 91 transfer rating).
On the OL, they added a name familiar to the Buffs in Jackson State transfer Willis Patrick, as well as former Crimson Tide 5⭐️ Tommy BrockMeyer at OT.
TCU was not the same team without RB Kendre Miller, who was nicked up for the national championship game. He is gone, and they have some youngsters they like and brought in Trey Sanders from Alabama, who had also reached out to Prime several times.
The starting TE toyed with leaving but returns for another year, which was a positive for them.
On defense, they lost their best DL in Dylan Horton, and their best LBer in Dee Winters.
In sum, there is a ton of 2022 production to replace, but the Horned Frogs did hit the portal well. Similar to CU, a lot of their success will depend on how these pieces all gel and also how well Chandler Morris mans the QB position. Both CU and TCU still seem suspect on defense heading into 2023.
