Let's review the deal and what's behind it:
Pats decide they need a receiver and a return guy (both obvious observations even us dumb fans can see). They don't want to go with the draft as they tried that last year with Jackson and he's been a bust so far. They look around at who's out there, and for whatever reason, none of the free agents appeal to them (Stallworth is always injured and now it's reported he's in the substance abuse program; they don't like Kevin Curtis or he doesn't want to come here, etc.). They look around and see who's a restricted free agent. What about Wes Welker? He'd be perfect for our offense to replace Troy Brown (he's a younger version) - he's a great slot receiver and a good returner as well. He burns us constantly and is the only good player Miami has on offense. We'd only have to give up a 2nd rounder, and let's face it, with 2 #1s, our 2nd rounder is house money at this point. It'll surprise the crap out of Miami and we'll get a guy that will have an immediate impact (unlike our most recent 2nd rounder). We put together a poison pill offer sheet, but are a little leary about pulling the trigger because (as others have pointed out), someone else (maybe someone wearing Jets green) will see the green light to "do unto others." So, we call Miami and say we're going to do this poison pill thing, but maybe we can make a deal? Miami, who wants to save face (over not being able to match the poison pill and the public perception that they were outdone by one of their most hated rivals) agrees. We end up getting our guy for the house $$ 2nd rounder we were alreadly willing to give up and a useless 7th rounder and can negotiate a better long term deal; Miami can say it was able to steer the big boys away from the poison pill and got an additional (albeit useless) draft pick out of the deal. Everybody wins, but especially us. Draft picks, no matter what everybody says, are mostly a crap shoot. I'll take a proven guy for a 2nd rounder (when we already have 2 1st rounders) any day.
