You can rotate JDM from DH to right and Collins from C, DH, 1B. Also if you can get JDM who really cares about Collins getting less ABs.
Or just don't resign Abreu and make Collins your primary 1B. Either way he isn't going to cost all that much, 22-24 AAV for his production on a 4 year deal sounds right. Still plenty of money to get pitching and a true RF as well.
