I think that's about right. Travis is more impactful in deeper leagues where compiling matters more. Bell probably is too. I think Renfroe and Margot are on their level because they have the potential to be impact players, even though they probably won't be.

I'm mostly in agreement with this arrangement, but I have a couple of concerns that give me mild hesitation.
1) I wouldn't be surprised to see Contreras get hit hard by a sophomore slump. The wear and tear of being an everyday catcher (and now catching a nutjob like Lester) I'm guessing will take its toll on his bat.
2) Velazquez is pretty injury-prone, but that may be functional. I'm suspecting he may be one of those pitchers who are excellent when they're healthy and on the DL when they're not. If you can replace him, he's more valuable in my opinion.
3) Bell could surprise and be the best of this bunch, but won't get enough HRs to make him an elite 1B.
4) Renfroe and Margot are both BA risks, but should have very long leashes, which will help with counting stats.
