Si,
Coleman was actually a great trade. And somewhat of an outlier. (Also a player that many, including myself, have been very pleased, if not surprised, by how well he has done.)
But when you aggregate all the wasted $$$, wasted years, wasted opportunities - and garbage players like Lacey and Joekel that we dealt with....if the upside ON SUCCESSFUL DEALS...is getting a Coleman - then your non-drafted player acquisition strategy sucks, (excluding UDFA rookies)
The downside is something like dealing with $30M in lost cap space, maybe more. Is the upside apparently a very good slot corner? When it works out after every 5th or 6th blown big dollar FO move?
The cost of these misses vs the value of the hits is pretty poor. Which leads to the issue - it isn't the players picked but the strategy this FO uses in trying to score these players for potential trades and acquisitions. Too much on potential and not enough on actual ability.
Most of these terrible trades shoot for great athleticism. They were also often high draft picks that did not pan out. Coleman was a good trade for a player that was good at what he did. Much less of a 'shoot for potential' 3pt heave from mid-court the FO generally tries for.
(And again, the admittedly, the worst moves by this FO have been the guys they let walk, since the people we replaced them with eventually (in aggregate) end up costing us more anyway. )
Yes, the FO made a great move with Coleman but it is the tendency of this FO to swing for the fences that leads to trying to get the guy that led to Kam holding out, or Joekel costing us big dollars, or whatever else. But I stand by my assessment of this team's FO ability to make player acquisition moves because contrasting the # of losers + cost of the losers with the total aggregate value of the big winners in the past few years....Coleman is not going to make up for that.
TLDR (for those not into multiple paragraphs):
This team has a problem evaluating active players in the NFL. It also tends to overweight the value of being a high draft pick at one time. The very fact their big success in the past several years is Coleman, contrasted to their big failures, means they suck at this.
