I like both but Joeckel is more athletic and more upside. Jake has a good blood line though in being Bruce son.
There's a reason why Joeckel played LT and Matthews at RT. Joeckel is the better player.
Not at all a knock on Matthews, because he's also a good player with amazing bloodlines, but I'll take Joeckel any day.
Joeckel is the better natural LT, with the higher upside in terms of elite pass blocking skill.
That is the most valuable aspect of being a LT, so I'll take Joeckel any day of the week.
