Agreed, and unfortunately for us starting goalies and top defenceman are not readily available in free agency.
Fortunately, we have an abundance of potential and current top 6 wingers. Between AA, Mantha, Svech, Bert, Zadina, Hirose, Ras and Berggren, something has to give in the coming years. Whether or not Ras, Berggren or Svech become what we think they can be, there is also plenty of free agents we could sign to fill those roles.
Depending on how hard Zadina/Hirose/Svech and Ras can push for top 6 roles and cement themselves there, I fully expect Yzerman to move one of our wingers by next years draft. One of Mantha and AA seem like the most likely to be moved as they would return the greatest asset and obviously have expiring RFA contracts.
This is exactly what the Red Wings should hope Yzerman brought from the Lightning, and why I disagree with the notion that they team can have too many wingers. That ability they had to keep pulling rabbits out of a hat with forward depth from both the draft and through college UFA's is what helped them get those allusive goalies and Dmen... Guys like Conacher, Johnson, Gourd, Palat, Point, Namestnikov, possibly Cirelli now, etc. Those guys kept coming in and making other forwards expendable, and then either they themselves or the player made expendable are traded to fill those spots on D. A lot of Tampa's better D and goalies can be traced back to excess forward depth and expendability:
Vasilevsky - Holland wants Quincey, but Colorado won't deal him to Detroit. Yzerman steps in and sends still productive yet regressing Steve Downie for for him, and then trades Quincey to Detroit for what ends up being the 19th overall pick they used to take their current and long term starting goalie
Bishop - Yzerman end up with two rookies that make a splash during the lockout shortened year (Killorn and Conacher) as well good extended looks at Johnson and Palat. He deals the rookie forward with the riskier longterm outlook and a 4th rounder to acquire a somewhat cost controlled starting goalie
Cernak - Basically strings from the last one. Vasilevsky made Bishop expendable, so Yzerman deals him and gets Cernak as part of the return.
Sergachev - They draft Drouin at #3OA and Yzerman takes a patient approach. While Drouin's back at junior in his D+1, the Lightning get 2 breakout rookie forwards in a 2nd consecutive year with Palat and Johnson, and Kucherov looks promising after finishing the year in the NHL. Drouin comes over the next season, but is overshadowed by the breakout of Kucherov. Namestnikov also comes up that season. The next year, Drouin struggles with an injury and gets suspended for not reporting to the minors, and instead of panicking and dumping him, Yzerman just remains patient. Meanwhile, Namestnikov has a decent first full season. Drouin returns and has an excellent playoff. In the next season, he breaks out, but at the same time Kucherov puts up an elite season, Point puts up an unexpectedly impressive rookie season, and Gourde finishes the season on the NHL club with 5 goals in his last 8 games. Drouin then becomes expendable enough to deal for Sergachev in a trade where if Sergachev doesn't make an immediate impact, the Lightning get a 2nd rounder as well.
McDonagh - This one basically continues from the Sergachev example. Gourde has an impressive first full season, Point and Kucherov continue to improve and Namestnikov has a break out 20 goal season. Namestnikov is then part of the package to bring in McDonagh and JT Miller. Then of course after Cirelli has a good rookie year, Miller gets traded to open up cap space and recoups the value of some of the assets traded along with Namestnikov in the initial trade.
That has to be one of the biggest keys to the Lightning's success with Yzerman. Look at their D for most of last season (which was pretty much Yzerman's doing). A #2OA that was drafted before Yzerman got there, the 3 guys acquired in trades mentioned above, a high end UFA signing in Stralman, and depth in a UFA buyout reclamation project in Girardi and a veteran in Coburn that they paid a decent price for a few years prior. No Yzerman draft picks whatsover (other than Koekkoek sitting in the pressbox), and it wasn't even an issue.
