I guess there are two different complaints:
IKF likely being the primary 3B
IKF getting 7.5M a year
The first is a legitimate concern for a contending team, but there are a lot of 3B options to throw at the wall if he doesn't look good.
The second is silly. 7.5M on, say, a luxury bench piece the team thinks is highly likely to give them 1-2 WAR while playing multiple positions is not a problem. That's middle reliever money.
Attaching Otto Lopez to any of these complaints is just weird. You don't want Otto Lopez on your 40-man roster.
