what do you mean 'penchant for getting hurt'?

Last season he got a concussion from an illegal (uncalled) head shot from the Seahawks. What other injuries are you referring to?

Wolford has been in the system for 3 years - has taken multiple practice reps, some preseason (2019?) and regular season action. He will be ready to go. During the season most backups get almost no reps yet are expected to come in and start - sometimes at a moment's notice. I'm sure he'll be fine without the preseason, fake 'games'
