In evaluating a draft trade, I first look at the trade value before I look at the players selected, since the success of such is unknown at the time. The Packers had pick #30, they wanted pick #26 to assure themselves of getting Love, they used a late 4th round pick to accomplish that. If you look at a standard draft value trade chart the Packers used 658 trade value points and got 700 in return. On a pure point value, the difference of 42 points is equal to pick #130. Great trade for Gute.
But you want to call it a bad trade, because the Packers gave up a 4th round pick, so you gave me a list of successful 4th round picks by the Packers. First, you listing 4th rounders that were successful as a reason to call it a dumb move is no different than me listing 4th rounders that weren't successful. Except for one thing, to be more accurate and fair about your claim, we need to look at just how many on your list of "successes" were picked at #136 or later?
Let's look at your list:
David Bakhtiari: #109
Josh Sitton: #135
T.J. Lang: #109
J.C. Tretter: #122
Brady Poppinga: #125
Davon House: #131
Mike Daniels: #132
Blake Martinez: #131
Hmmmmm.....absolutely none of these guys were selected with a #136 pick or later. But I guess the Packers could have just traded up to get them? Oh wait.....
