They didn't really have any other options with the scholly so why not? I see Lawrence the same way.
but, that is not accurate. w. herrera the choice was leave the 'ship empty or fill it with herrera.
lawrence is completely different because he has to sit out the year, and they aren't low on bodies or on 3s, so it's not like he's needed for practice.
so regardless of whether you take him or not, you get nothing in '10. taking him is the equivalent of an '11. the choice is take lawrence or take an '11.
