Again, there's no basis for that statement. 3-4 year contract for a FA guarantees that 50-75% of that deal is A) wasted salary on a losing team, and B) wasted minutes that could have been given to other developing players. I don't understand your concept of value.
This mentality is the same that thinks George Hill's deal was a good idea. Literally the only way your mentality makes sense is if you think this team is like, 45 wins and is a Lavine type addition away from 50 and getting the 8th spot. If that is where you're coming from, then that makes a lot of sense, even if it is a completely misguided and incorrect assumption. If not, then it makes zero sense to sign a free agent with the intent on making the team better at this point in time.
