I'm with you to a point.
Keep in mind...
Average NFL WR height is 6 FT according to worldmetrics.org. In 2021, NFL.com says around 5-11 193 is the average height and weight of NFL CBs.
Michigan, NC and best D in college, just started a 5-9 CB for multiple seasons. Mike played fantastic and was drafted in the 2nd round. Mike Sainristil. 5'9" 182 lbs | CB | MICH. 2nd Round 50th Overall. Career Stats (62 games)-108 TAK (70 solo), 10.5 TFLs, 3 SACKS, 7 INTs, 13 PD and 2 FF
Sure 5-10 can be a disadvantage vs taller guys like AD Mitchell, Wingo and Livingstone. But it wouldn't be a concerning height mismatch vs Bond, Bolden, Golden, Cook and Moore.
5-9 Quandre the Giant Diggs had a nice TX career. Had 1 game vs TCU where it was a height mismatch downfield. Still had a great NFL career.
TX commit Caleb Chester CB is listed at 6-1 and 6-2. But Caleb might be at a disadvantage vs the quicker and faster WRs.
Devin ran a 10.65 100M as a soph. Devin is still young so he might make 5-11 and weigh 190. His floor is probably around 5-10 180. Watch his JR highlights, he can play.
If we aren't getting Sanchez or Brew or Lee OOS, speedster Devin Williams might be the right complement to 6-2 Caleb and hopefully Kade Phillips.
