This could help the Eagles.
Per Bob Glauber of Newsday:
“The Rams would likely move Saffold to right tackle if they signed Long, and Saffold probably doesn’t want to move off a more lucrative position. Saffold is entering a contract year, and left tackles make nearly double the money — on average — that right tackles do. St. Louis considers Saffold a strong starter and does not want to lose him. How this plays out might get interesting.”
The Rams could offer Long a deal to play RT, but you wonder how much they would pay, knowing that Saffold will need a new deal next year. The Rams might decide leaving Saffold at LT is the way to go and they’ll just add a RT in the draft. They do have a pair of 1st round picks.
If Long leaves STL, the market for him would be wide open. Stay tuned.

Would you rather have him than Vollmer?
Long is younger and might be cheaper, but I think Vollmer is the better RT right now.
