Tim Tebow the tight end’s stock is down after his NFL preseason debut. Tebow had notable trouble blocking on multiple occasions.

Jacksonville Jaguars legend Tony Boselli joined Colin Cowherd on Monday and shared that Tebow’s blocking struggles were not surprising to those who have watched him in training camp.

“You can see in camp too, he struggles to block,” Boselli said. “You can say he was a physical quarterback. That’s great. Being a physical quarterback is one thing. Being a physical tight end and playing in the trenches and having to block and move people is something that’s much more difficult. He’s just not shown a propensity to do that during training camp.”

Boselli also shared a telling observation about Tebow’s standing in the tight end room. Tebow was the only tight end to not contribute on special teams.

“I think the most telling thing for me is he was on zero special teams,” Boselli said. “If you want to be a down the line guy who plays tight end, you better play special teams and be good at them. He was the only tight end who didn’t have any reps on special teams in the first preseason game. I think that’s very telling.”
