I love this signing. I might be Alaric's biggest fan on these boards!
He is not a Hall of Fame player. We aren't getting another Whitworth, or a Trent Williams. But AJ rarely if ever gets beaten. I can count the number of times I remember him being beat clean and badly with a clean line to Stafford on one hand. Speed rush. Power rush. Stunts. Elite edge rushers opposite him. It does not matter. He finds a way to get the job done. He is good at pass protection and in the run game. He is still pretty young (26, but will be 27 by the time next season stats) and is a late bloomer that appears to still be ascending. I don't know if there are 10 LTs that I would take ahead of him. I think he is that good - a player that likely rounds out the top 10 at his position, or at worst, falls just outside of it.
LT is a hugely important position, that commands big money on the open market. With the cap set to go up, and AJ having been our starting LT for years now making literally peanuts by NFL standards, I am surprised he signed for this much money at this point in time. Great deal for the Rams. If we signed him after free agency, his value only goes up, lots of LTs are going to really get paid I think with teams having extra cap room.
Unlike when we gave Noteboom a ton of money, A. Jackson has a very good sample size and body of work. You can sadly never tell which players will mail it in once paid. As long as that doesn't happen, I think we have locked up a stud!
