I don't know whether we will or won't be a major player in FA when it opens. I suppose the answer lies in your definition of "major." To me, most associate that label with the Redskins of the league who dominate the early in the process, giant sticker price signings. I have no interested in that kind of "major," and few people I know clamber for that kind of recognition.
Are we talking major in the sheer numbers of signees, where there are several to many people brought in, even if their star power and salary cap hit is minimal? Lots of people like to relive the Patriots signing of over a dozen perceived to be marginal FA's enroute to a SB win a little more than a decade ago, but how many teams consistently use this strategy to dramatically improve their roster? It seems to me that this is a depth improvement strategy where you're looking to enhance the bottom third of the roster- it matters because in stretches those 3rd stringer need to play a lot and perform at a similar level to your starters... We did see TT take a stab at this a couple years ago with the Merling/Hargrove pre-camp strategy in the hope that we'd find some rotational depth and impact. It didn't work out, but it also didn't hamstring us cap wise. I think trying this more regularly means the odds that you hit go up simply because you play more, but we get similar looks at players through undrafted free agency, which is a staple of our personnel acquisition MO under TT.
Then there's major in the sense that the guys you sign deliver tremendous value for the dollars you spend on their contract. Everyone is familiar with Charles Woodson as an exemplar of this, and to a lesser but still significant extent, Ryan Pickett has been a great value overall. I would have to say that the frequency of these kinds of "major" is really low league wide- perhaps only Reggie White was a better defensive FA in quality of play and impact on the rest of the defence in NFL history. I think there are few instances like Woodson because the conditions for signing someone like that at a dollar value that makes sense are so rare- there were a lot of names at the time he signed with us that were similar, if not bigger, in terms of marquee value, so he wasn't the one FA everyone had to have. There were serious questions about Woodson and whether he was done at the time we got him too.
Perhaps the only FA in his prime that remains an elite player after big money I can think of over the past several years is Vincent Jackson, who was a stud in SD, and remains one in TB. Apart from that, big money signings rarely deliver great bang for the buck.
Many will point to Percy Harvin and Cliff Avril as great examples because they made plays in the SB for Seattle, and perhaps those plays and that win will justify their collectively enormous price tag. I think it may be just as likely that those signings become millstones to continued elite competiveness for the Seahawks- Harvin is an injury machine predating his time in Seattle, and Avril is streaky at best. You really need big money players to deliver consistently for their contracts to be worth it, and to date, neither of them have provided that high level consistency. Past history says they are unlikely to start doing that either.
I would like to see TT target players that provide proven fixes for longstanding issues. Solilai has been mentioned as a potential target. I think he's a lesser talent than Raji, but he's more consistent, and he made the Fins 3-4 work. We could use that, and he's a solid citizen and teammate. If the market doesn't drive his price beyond something ridiculous, is $5 mil a season for 4 years really a bad deal for someone you can plug in at NT in our base and get consistently effective play from? I don't think you need to plug several holes with big money deals, but I think if you can tackle one significant issue per offseason this way with an affordable price tag, your drafting really becomes a developmental operation because you're not forcing young guys to be really good when they're not ready- they get to watch and rotate under players who give you the consistency you need, and that rubs off.
There are off seasons where I think TT would be wise to be more active, and there are off seasons where I'm perfectly happy to watch them all fleece opponents for contracts they won't deliver on while we stay put in great financial shape. This year, I think where we're drafting there are likely to be really good options on 3-4 DE's, potential OT's (Taylor Lewan may be around when we draft, and the kid from Tennessee could be the second coming of Chad Clifton), and interesting LBs. I'd really like to see us solidify one spot so we can narrow the focus of what we're looking for in the draft. To me, that would make FA "major" this offseason...
