This would be a play for this year. It's a keeper league where we keep the round that the player was picked in. Vorachek is a good value at a 10th round but i also have Crosby (1), Backstrom (4), Benn (7), Holtby (6). I also have Malkin but can' keep him. We count Hits and BS.
The reason for this deal for me is two-fold. I'm not confident vorachek will finish strong and i have a good chance to win and also i have the top 3 in the league in assists and need some goals.
Without knowing any of that, it's hard to say whether it makes sense for you to do this. I think Cek and Perry will be on the same pace to finish the season... if you really have an abundance of assists, then I would probably gamble on Perry for the G and Hits.
