redshirting juniors is tough, unless you inform of redshirt in recruiting. this is harder today due to the more intense competition, but still, there are MANY juniors i've recruited over the years, who i'd only take if they took a redshirt. maybe they need it for growth, maybe to align with classes right so they are there as senior in our important title-seeking year. i have informed of redshirt a couple jucos in 3.0, its still definitely a viable strategy.
