League average player? His floor is Moustakas and his ceiling is 5+ WAR. I like Seager a lot, but I think you're overstating him. Seager's floor is probably around the .673 OPS he put up in 2018 (Moose was not been under a .774 OPS since six years ago). I'd probably say Seager is a bit above average. I don't expect the 5.0 WAR seasons he had 4-5 years ago. He's 32 years old - most players don't suddenly revert to the 27 year old selves. But I think he can still be good. A change scenery, better health, etc., can really help a guy. And more importantly, getting out of Seattle will help. For his career, Seager's OPS away from his home ball park is .799. At home it's .732. I would expect him to improve getting into a more friendly hitting environment such as Miller Park (or whatever it's called now). I definitely think we'd have to protect ourselves financially if we traded for him. But I would be okay with Seager as our 3B if something could be worked out.
