I am getting at the fact that I don't think if that trade was somehow accepted, it would get passed by the TC.

I haven't played a keeper league before but from my year to year leagues I have always found some great gems in the later rounds of the draft.  Same with some full sim leagues too.  I would only assume its the same. 
I already made a very similar deal with Robo.

Willing to trade my 10th, 9th and 8th round picks for a 4th rounder.

gets 3rd round pick
gets 5th, 6th, 7th round picks

I have been noticing there are some discrepancies between the league page and Fantrax.  Which do we go by? 

Just my 2 cents.  1) Stud RW are much harder to find than Centers. 2) Stewart has only played 2 years in the NHL and has improved every year.  3) Stewart hits more 4) If you look at the production from last year Stewart was scoring at a higher pace per game.  oh and 6 million cheaper. 

The other thing I will point out is that Cho34 is currently running 15 fantasy teams. It is not like he is a newbie.
