I hate to say it but. No one likes training camp and maybe, just maybe Hartline thinks he is a lock and could afford to take camp off? Just a question/thought? But I agree he will not be game ready physically. Mentally he should be fine.
Not likely for someone in a contract year. That usually happens with a high paid vet that doesn't want to risk injury in preseason.
Not someone playing for their second contract. Beside Harline has a chance to make as much this year as he has the 1st 3 seasons.
