What are the chances of the Ravens signing Wes Welker?

It's that time again to click open our weekend Baltimore Ravens' Twitter mailbag ...

@jamisonhensley: I wouldn't say great, but I wouldn't rule it out entirely either. Welker is the biggest name left in free agency, and the Ravens were one of three teams listed as possible landing spots by ESPN's Field Yates. It really boils down to how much confidence the Ravens have in Michael Campanaro being healthy and productive this season. It was evident how much it helped the Ravens offense when Joe Flacco had a shifty target like Campanaro in the slot for a few games last season. And before anyone mentions about the upside of Kamar Aiken and Marlon Brown, it should be noted that the Ravens ranked last in the NFL last season in receptions by players who lined up in the slot with 62 (the Saints ranked first with 144). The problem is, Welker has a scary injury history. He's had three concussions over the last two seasons. That's why there is a good chance that no team will sign Welker. @jamisonhensley: I don't see the Ravens putting the franchise tag on left guard Kelechi Osemele. My prediction for the tag in 2016 is kicker Justin Tucker. Ravens officials probably know they're going to have to make Tucker one of the highest-paid kickers, but it could be tough to reach a deal when St. Louis' Greg Zuerlein and Minnesota's Blair Walsh are looking to cash in as well. There is no chance of the Ravens letting the NFL's most accurate kicker walk away, so the franchise tag might be the only way Baltimore can keep him. Tags on kickers are the cheapest of any position, and it would cost the Ravens about $4.5 million. The Ravens have a cheaper alternative at guard in John Urschel, a backup in 2015 who started a couple of playoff games last season. Tags for offensive linemen were over $12 million in 2015. So, it just makes financial sense to use a tag on a kicker. @jamisonhensley: Perhaps I'm being overly optimistic, but I believe Joe Flacco and the Ravens will get this done before the new league year in March. There's just too much motivation on both sides. The Ravens don't want to let go of a franchise quarterback after not having one for the first 12 seasons of their existence. Flacco enjoys playing for a perennial playoff team and living close to his family in New Jersey. There's no doubt that the Ravens are going to make Flacco one of the highest-paid players in the NFL again. This time, however, the Ravens don't want the cap hit to nearly double after the third season. They want a six-year deal to last six years, which means getting Flacco's cap number should range between $19 million and $23 million over the length of the contract. When it comes to extending contacts, history shows that general manager Ozzie Newsome almost always gets it done with players he wants to keep.
