I would take Harvey. Kid looks like he's in for a big season (I'm thinking similar to Dickey last year) and his numbers last year were good so it's not like he's a plug on a hot streak.
I like Samardzija but he's nothing special.
Wilhelmsen is off to a hot start but don't see it continuing all year (guess some people say that about Harvey too) but he's on pace for a 44 SV season, very doubtful that'll happen. The ERA and WHIP will come back down to Earth. He's a good candidate for a sell high scenario.
