I finally figured out everything that went into the Rosen trade.
Now if you don't like getting Rosen, none of this makes any difference, but just watching what the front office did to effect this trade is enlightening. There were two steps.
STEP 1: We traded with New Orleans.
We traded down with our 2nd round pick at 48 for their 2nd round pick at 62.
We traded down with our 4th round pick at 116 for their 4th round pick at 202.
We then get their 2020 2nd round pick.
This is a good trade for us because we still have selections in the rounds we traded in and we get an extra 2nd round pick, albeit for next year.
STEP 2: We trade with Arizona and they demand a 2nd and a 5th for Rosen.
The trade with New Orleans let us maintain a 2nd round pick, and give them one of significantly less value (62 in place of 48) and our 5th at pick 151 remained unchanged. We met Arizona's demand, but reduced the value of our 2nd round pick before trading with them.
The end result of all this is we started with a trade that took us from 2 picks to 3 picks with one of those picks being next year and not losing a round to pick in this year. That yields us a gain of 1 pick. Then we ended by trading 2 picks (a reduced value 2nd and a 5th) for what was a 1st round pick last year (a loss of 1 pick).
In effect we did not lose a pick in this trade. You can think of it as using last year and next year as a kind of debit and credit deal. If Rosen doesn't pan out, then we lose on the debt part of the deal (2018 draft position) but we are still in a position to use the credit part of the deal (2020 draft position) to replace him. If our 2020 pick pans out then we haven't lost a thing but basically ended up with 2 picks for the price of one pick. If Rosen does pan out, then we are ahead by one pick in 2020. If that pick pans out we are batting 1500.
Anything we can get for Rosen in trade turns out to be pure profit. We have just made chicken salad out of chicken poop. All this has been done while enhancing our next draft WITHOUT TANKING.
The Front Office really shined in this set of transactions. I am impressed!
