Depending on team needs and depth, it is a fair trade.
Two catcher league? If so, makes it closer to fair. A one catcher league I would think Lawrie has much more value than Arencibia.
10 team? Garcia is not really rosterable, and Seager is borderline, so you have a good player and a borderline rosterable for a better player and a non-rosterable.
I would probably take the Lawrie side but I can see an owner being frustrated with him (I am a Lawrie owner in two leagues, and I traded him in a third).
