Such a great legacy he’s left behind.’’MIAMI — Wes Welker has a history with Super Bowls. Do they play tough? Welker, who went undrafted during the 2004 NFL Draft, signed as an undrafted free agent with the San Diego Chargers. Nobody cares about Welker's 11 catches for 109 yards in Super Bowl XLII, a superb performance that was forgotten amid David Tyree 's improbable helmet catch. But he was unable to haul in the big one.“We wish he didn’t, but he did, and he did a helluva job,’’ Welker said. Welker was on the team when it went to Super Bowls XLII and XLVII. He lost two Super Bowls as a member of the Patriots, both defeats sealed by late fourth-quarter Manning-led drives. And understand what (the Chiefs) are doing. It’s fun being around him.”Maybe it’s not always quite as fun to play under him. He bought in.”When speaking about the attributes he values most in a receiver, Welker sounds like Miami coach Brian Flores, and, for that matter, the Patriots’ Bill Belichick.49ers players say they are impressed by the competitive juices Welker shows in practices and on game day.“Deebo Samuel, he’s playing like a Pro Bowl-caliber player, not a rookie, and a lot of that’s attributable to Wes,” said veteran San Francisco receiver Emmanuel Sanders, who actually played with Welker in Denver.Samuel was fast and strong and physical and played fast. 0-1.

If he does, the Patriots have a first down on the Giants’ 20-yard line and everything changes.

And be able to separate and get open.”And Welker, the former receiver for the Miami Dolphins, New England Patriots and Denver Broncos wasn’t letting it happen on his watch.Welker has proven to be an excellent fit for 49ers coach Kyle Shanahan, who snagged him from the Texans, where he had paid dues as a lower-level assistant for two years.“At least when people ask me how many Super Bowls have you won I can at least say one,” Welker said.

Head coach Marty Schottenheimer later acknowledged that in terms of roster cuts, releasing Welker was the "biggest mistake [he] ever made".

But you’re only the biggest mismatch on the field if you block the hell out of somebody. Guys that practice hard every day.

And then after practice, we’re going to run some sprints. Welker made it to another Super Bowl, with the Broncos, following the 2013 season, but his team got hammered by the Seahawks.Thanks for contacting us.

But …

Until you start doing that, you’re not really worth a damn out there.”Welker answered a lot of questions this week about, very surprisingly, not having a Super Bowl ring (he lost twice with New England and once with Denver, most due to bad timing). I tell him all the time, because of his size, I tell him you’re the biggest mismatch on the field.

Showing him those minor details of finishing blocks.

Welker got both hands on the ball but could not secure it.

And we’re going to keep that weight off. Miami had done the right thing by signing Welker as an unrestricted free agent.

He caught seven passes in Super Bowl XLVI in Indianapolis. Welker made it to another Super Bowl, … “There are a lot of great memories in my three years that I played down here. “I had been a fan of the Patriots’ offense.

Credit to him. “He has an amazing career and obviously one of the best quarterbacks of all time with what he’s accomplished and what he’s done. He caught 903 passes and is the only receiver in NFL history with at least three 110-reception seasons and he is the first player to have five 100-reception seasons. Welker made the Chargers out of training camp, but was released after the first game of the season when the Chargers claimed safety Clinton Hart off waivers. But they had done the wrong thing by dealing away one of the best slot receivers in NFL history.“I was nervous about the weight,” Welker recalled this week.

He tied what at the time was a record with 11 receptions in Super Bowl XLII in Glendale, Ariz. And see fast. “He led some two-minute drives there at the end. He’s out there screaming just as much as any other player.

Being able to execute. “Getting him to realize how important every single play is.

Welker, who reached five Pro Bowls and three Super Bowls and posted five 1,000-yard seasons in the NFL, has credibility with his players because he’s done it — and he’s willing to be alongside them for things like sprints.“Knowing the coverage would be a great step,” Welker said.

The drop forced a punt, Manning took over and the rest, as they say, is history.The receivers under Welker’s direction know all of this.Wes Welker has a history with Super Bowls, the Giants and Eli Manning.“Yeah,’’ Welker said, and shrugged.Wes Welker has a history with Super Bowls and the Giants.“Absolutely, I express it all the time,’’ Welker said.
