A good LT is way more valuable than an All-Pro guard.
We've always known Tyler was a mauler in the run game, the big question has always been, how much will the pass blocking develop and can he do it in space out at tackle. If he can get to where he can do that at a high level, then he should almost certainly move out to LT. Obviously, it depends on who else is on the roster.
I think they're doing the right thing with him this year, though. Tyron should be starting at LT when healthy (I know, I know), and they're better off not bouncing Tyler in and out. But making him a tackle should be the long-term plan.
