While I agree with the Liles/Komi argument, I disagree with the bolded part.
Grabovski may not have been drafted by the Leafs but he has been developed by us. He bleeds Blue and White, and for you to make a judgement like that before ever seeing him play in the playoffs is nonsensical. I don't remember the last time I seen Grabo take off a shift. He makes the players around him better and he's now in his prime. I don't know about you but I'm tired of trading away players that we developed, especially for the reasons that you listed.
Quick question: Who do you see us winning a cup with?
Honestly? Phaneuf, Rielly, Gardiner are core pieces. Gunnar as a 5/6. We need another top dman and a better top 4 dman to really survive. A system needs to be put into place however as well. Goaltending is an issue. We won't win with Reimer/Scrivens.
Forwards are a bit more difficult. Look at the forwards from the previous cup champions.
Kopitar/Brown/Richards/Carter/Penner/Wlliams
Krecji/Lucic/Marchand/Bergeron/Peverly/Ryder
Toews/Kane/Sharp/Hossa/Bolland/Versteeg
We do need a system. Maybe a more structured game can see more results. I think if we win a cup, Lupul might be on it. Komorov/McClement as fourth line guys. Kulemin potentially as a third liner. Maybe JVR as well. But even Kessel. I don't see us ever winning a cup with Kessel as our #1 player. He's too shy physically to compete in the playoffs as the #1 guy. I know people will point out his stats in Boston but the truth is, he wasn't the main guy. The same reason he went +30 during that season. Teams didn't focus on him. We can see it when teams focus physically on him. He's not a physical guy. He gets pushed around. Maybe we win the cup with Grabovski as our third line centre, But I don't see it as our number 2. I know people like him here. I'm not. To each his own. I was never a fan of him to be honest.
Look at our team now. We aren't even close to a playoff spot, let alone a Cup. Major pieces have to be added especially in the centre position. We need a forward who's great defensively. Look at the previous cup winners. They have amazing shutdown centres. Bolland/Sharp, Staal, Datsyuk, Bergeron, Richards. Defensive minded centres that are fantastic. Grabovski doesn't really fit that profile.
