You did warm him up with all the lunging then putting the saddle on and lunging him more. He should be shedding a bit, not like in Spring, but short hairs which indicates his winter coat is coming in. It actually begins a lot sooner than a lot of people realize. Some breeds and/or coat colors coat up at different times. If you put him in cross ties to boot him, he may paw as he's a bit concerned about feeling trapped. I never tie, just drop the lead. Because the horse knows he can escape, he'll stay. You do need to teach him this.
