Redshirting is becoming a rarity. Most players are unwilling to 'waste' a year sitting out and developing their craft and prefer learning on the court. In the portal era, most programs are unwilling to waste a scholarship for an extra year of an 'unproductive' player. The attitude is to see what they got then move on to another player if it doesn't work out.
I much prefer the good ol' days (still less than a decade ago!!) when both player and program were committed to one another and invested the time to build the relationship during recruiting AND during the 4-5 years that the student was with the program.
