Free-agent wide receiver Wes Welker is heading west, as the Pro Bowler has reached an agreement on a new contract with the Denver Broncos, according to ESPN's Adam Schefter:

Wes Welker has agreed to terms with Denver Broncos.

Schefter added that Welker's deal is for $12 million:

Wes Welker lands a two-year, $12 million deal from the Broncos. Demaryius Thomas, Eric Decker, Wes Welker. Have fun, Peyton.

Broncos vice president of football operations John Elway confirmed that it's a two-year deal for the veteran wideout:

Agreed to terms on a 2-yr deal with Wes Welker. Excited to have Wes join the Broncos. His production & toughness will be a great asset!

NFL.com's Albert Breer shed light on the deal the New England Patriots offered in an effort to keep Welker. As CSN New England's Tom E. Curran notes, a source close to Tom Brady was furious that the franchise failed to put forth an extra $2 million to keep the Pro Bowl wideout:

Let me do tweet 1 more time, with his name ... The Patriots' final and only recent offer for Wes Welker was $10M over 2 years, w/incentives.

Spoke to someone close to Tom Brady. Beyond enraged at contract details that netted Broncos Wes Welker. "Disgrace""disservice" were used.

The enraged party in my previous tweet was someone close to Brady. Not Brady himself. Got no idea how he feels. But I bet I could guess.

Welker has been one of the best and most productive wide receivers in the NFL over the last six years. 

After spending his first two seasons as a No. 3/slot receiver with the Miami Dolphins, Welker emerged as one of the greatest weapons in the NFL with the Patriots.

With Brady as his quarterback in 2007, Welker put up 112 receptions, 1,175 yards and eight touchdowns for a Patriots team that had an undefeated regular season and went to the Super Bowl before losing to the New York Giants. 

Proving that his breakout season was no fluke, Welker had 111 catches, 1,165 yards and three touchdowns in 2008 with Matt Cassel, who replaced the injured Brady in the first week of the season. 

As the years went by, and he kept putting up numbers, the debate about Welker's place in history began to take shape. He has only had one season since 2007 where he didn't catch at least 111 passes. That was in 2010 when he had 86.  

The Patriots devised a perfect plan to use Welker. Given his physical limitations at just 5'9", he was never going to be a downfield threat. Bill Belichick basically used him as a pseudo-running back to pick up grunt yardage. 

Since he will turn 32 in May, the window of opportunity for Welker to cash in on his success the last six years was rapidly closing. He was designated with the franchise tag last season.

In Denver, he'll pair up with Peyton Manning and a dynamic pair of receivers in Eric Decker and Demaryius Thomas.
