Teams rarely trade players!
Now this year has been more active then in years past so maybe things are changing.
Cards trade a 7th rd pick for Foster
Seahawks trade a 6th rd pick for Adams?(or was is Hand)
Cards swap TJ for M. Walker
Pats trade 4th for Washington
Redskins trade a 4th for Trung C.
Then figure in the picks given up for FA's
Falcons give up a #1 for Price
Redsins give up a #1 for Coles
I know I'm forgetting some others.
Now to long ago the Rams gave up 2nd and 5th rd picks for Faulk. Talk about getting huge value for draft picks.
What does all this mean, well in almost every case the team that gave up a draft pick was either filling a position of need or felt they were getting a superstar.
This brings us to why the Pats gave up a 4th rd pick for Washington.
The Pats want and need to run a 3-4 defense a majority of the time. They don't have a serviceable NT on their roster. They had to get someone who could play this position or their season was going to be a crap shoot at best. So they did the right thing and got a 1 to 2 year fix at this position, good trade for them. The Bears are retooling and to get a 4th rd pick for an at best short term player, this was a good trade for them as well.
Washington is not a long term answer for the Cards nor is he likely a good fit on this team. In a year or two I would hope the Cards are in a position that acquiring a player like this would help put them over the top but at this point it won't.
If the Cards end the season with more than 2 mil under the cap I will start a thread stating that koolaide has been very very bad to me and that I'm an idiot. For now, I'm keep hydrating myself with this tasty beverage and wait to see how the season plays out.
