LAwrie hasn't done well in my leagues so far, at least not worth 7+ mil, whereas Young has from what I've seen.
Me, I have a Hosmer/Baker platoon doing well in Kaufman. I'm different from Vis and splinter, I don't see Boni as a great choice, unless you're facing tons of LHP. His side vs RHP is pedestrian.
I like Joyce better moving RJ to LF (one of my favorite cards so far).
For sure though 1B needs a change, I personally like your 2B, SS, CF and Rf/Lf (RJ).
Also, if it were me, I would drop a RP or 2 and pick up the last good * SP in Romero and just abuse your SP for as much as you can. Leaving Holland to take the rest, as much as possible. I'm getting by with that strategy on another team with Aceves sucking up most of the non SP innings to pretty good success (when my team hits).
