It was in a pretty weird way. The patriots don't really have any notable free agents (their core is remaining in tact), so using the tag on who is probably the 2nd best kicker in their franchise's history (Adam Veneterri, or whoever you spell it, is IMO the best one they had and is arguably one of the top-5 clutch kickers in NFL history). That being said, kickers are heavily undervalued in this league and can be picked up for practically nothing, so using the tag on him either shows that they have tons of faith in this guy or that they just got bored/didn't have anyone better to use the tag on.
It means that they think they can sign him to a long term deal before the deadline. Franchising a kicking specialist is silly otherwise.
It also means that Devin McCourty is asking for a lot, as they aren't as confident signing him long term and don't want to pay the franchise cost for one season. Dude's probably going to get close to $10 million a season, which... yeah, I'd let him walk.
I hope the Lions somehow find a way to sign Suh, otherwise they have no one to blame but themselves for letting it come to this
They can blame themselves for a lot. Including the inevitable Calvin Johnson cut (unless he throws them a lifeline like Larry Fitzgerald did).
I really can't see him resigning with them unless they outrageously overpay for him. Tons of other teams will probably make offers, and will be in much better positions to make the playoffs next year (aformentioned carolina/seattle, then there's Dallas St Louis and San Fran). Imo, the free agency class for this year will be one of the best ones of all time, with Peter-griffin-son and Murray being two good rushers and Suh/Hardy being two good (albeit risky) defensive players. That, and this is one of few years in which there aren't too many teams looking for a QB (St Louis Tampa Jets and Tennesee are the only ones I can think of, and three of those teams will probably push the draft).
I don't think anyone really considers Suh a risk, per se. Or at least I don't. With the way the NFL operates, he's not really in any danger of missing more than a game or two, no matter how many people he steps on. And it's not like he suddenly turned it on this season, trying to get paid -- he's always played and been paid well. The only problem is that he probably wants more money than he (or any defensive tackle) is really worth.
I am extremely happy that the Chiefs tagged Houston. It makes it more certain for Chiefs fans that he will stay, and if not we can always get draft picks from the team that he goes to. I just hope that this allows the two parties to come to a long term contract agreement.
Even though Houston is the only tagged guy who is even conceivably worth it, there's no way any team gives him an offer sheet. Believe me, if that happened with Demaryius Thomas, as much as I like him, I would pray the Broncos take the picks and cut bait.
That said, Justin Houston is most likely very very pissed about being tagged. I remember he held out as long as possible last season, and after a 22 sack year, he's not really any closer to a deal.
Also, I really hope that Demaryius Thomas and Dez Bryant play out their tags. Wide receiver contracts are going to go down in a hurry, I bet (with the inevitable releases of Percy Harvin and Mike Wallace, and Dwayne Bowe next year), and none too soon.
He may be a dirtbag, but him on that team would instantly make their defense even scarier (if that's possible). From what I read, Suh is apparently willing to take less salary if it means joining a "superbowl contending team", so joining seattle is technically in the realm of possibility (even though I'm highly skeptical he'll go anywhere other than carolina).
I bet his idea of "less salary" is $15 million per season instead of $16 million. Which, obviously, no contending team is going to pay.
ALSO NEWS FLASH:
According to Adam Schefter, the Eagles and Bills are going to trade LeSean McCoy and Kiko Alonso as soon as the league year opens (presumably straight up). It's hard for me to know what to make of this, considering McCoy is a proven commodity and Alonso simply had one very good rookie season, but my first impression is that Buffalo got hustled.
