Im not sure what Baylor's reputation is but Baylor is ranked 42 in the country in F+ to Colorados 70+.
The 3 non-TAMU teams ND has played are all ranked in the 80s & 90s ... (just to give an idea of the level of competition).
Colorado is only a couple seasons removed from winning just one game and finishing ranked 127th out of 130 FBS teams (back in 2022 the season prior to coach prime's arrival)
The fact that Colorado competed with a P4 quality team (regardless of the outcome of the game) is a sign that Colorado is getting pretty close to being a competitive P4 program themselves (if not there already)
And on another note, how many have watched a Colorado game? They are demanding the ball, talking trash to the other team, dancing after big plays, barking at their teammates, etc. they play with a lot of dominant energy.
