Niemann's stuff is legit, but his command is not as good as he showed in his first start. He will have some ups and downs throughout the year due to the command. Coming out of Rice, he just wasn't as polished as most people though and then the injury set him back over a year as well. He still needs this year to work on his command, so he can hopefully come into his own in the next year or so. As far as Hammel, he is just not very good in a starting role. He has a good fastball, but that is about it. He might could "possibly" work out as a 7th inning man due to his fastball, but he should in no way be counted on going more then two innings and having to face batters more then once.
