Potential offensive tackle targets
Trevor Lauck, Iowa

If Markel Bell doesn't develop over the course of the season, Philadelphia should consider a starting tackle in the first round to replace him. Bell could continue to get work as a swing tackle and continue to develop to potentially become the left tackle of the future at some point, while a first-round talent takes over on the right side.
Lauck is a very solid prospect from Iowa who is above average in pass protection with his balance, anchor, and footwork. In the run game, he's effective, but not a game-changer like Philadelphia is used to from their tackles.
Lauck is a left tackle in college, but based on his play style and athletic traits, I think he can move to the right side with little trouble.

But there's a chance Bell does develop. He has the size and coordination to stick as a starter. If he can up his game speed and start making plays instead of just preventing plays, the Eagles could have a starter already in the building.
And if that's the case, Philadelphia should still consider drafting a tackle on Day 2 to develop. I'm a big fan of Niki Prongos. Prongos has great size (6-foot-7, 310 pounds) and is a very natural athlete. He plays with great pad level and balance, and can get to the second level to deliver blocks.
He has a high floor as a player when he plays within himself, latching onto defenders with two hands and using easy, methodical movements in the run game. But when he lets loose, he shows a good punch with independent hands and the ability to make impressive blocks in space.
Prongos would be an intriguing developmental option if Bell doesn't work out long term, or as a future starting left tackle.
