QB 2? Texas Tech Officially Designates Castellanos as Backup Option - Yahoo Sports

Castellanos, who arrived in Lubbock just under a week before the season opener against Abilene Christian, had drawn speculation about whether he might push Hammond for the starting job. McGuire put that to rest directly. "It has been our intention since this past December to carry six quarterbacks on our roster this season. With Tommy, we have an experienced quarterback who we believe can come in and help us win games, if needed," McGuire said.

For Tech fans, the clarity matters. Quarterback controversies have a way of becoming locker room distractions, and McGuire's statement draws a firm line before a single snap of the regular season is played. Hammond is the guy. Castellanos is depth, not competition.

The timing is tight. Castellanos has days, not weeks, to learn the playbook and get comfortable with his teammates before the Red Raiders take the field. Whether a fifth-year transfer can absorb a new system that fast and actually be ready to step in if Hammond goes down is a real question hanging over Jones AT&T Stadium as fall camp wraps up.
