I don't understand people who are keen to give up Jurco. They guy has just as much potential as Nyquist and maybe only a bit less than Mantha. He's 6'2, is willing to play the body, has fantastic hands, and is a solid skater. Plus he appears to have very solid work ethic. His improvement year 1 in GR vs year 2 was remarkable. He's only 21, and has already broke the Wings roster. I mean much like the other two, he could totally bomb out, but I think his potential is definitely 1st liner. I wouldn't trade any of those 3 unless I was getting a legit young 1st line forward back.
Sheahan, Tatar, and Pulu are all in the tier below those 3. I think they all top out at 2nd line players, that more compliment than carry a line. Tatar reminds me a bit of a Kozzy type player. Has good skill, competes well, and probably gets you some clutch goals. Sheahan has very nice hands for a big defensive guy, but I'd be shocked if he ever scores more than 50pts. I don't think he'll ever focus enough on offense. Pulu is a guy I feel will be a 2nd/3rd line tweener that can dominate a PP, but needs match ups 5 on 5. Those are all guys I'm willing to give up if a good deal came along. Tatar probably has the most value, and will command the most money the soonest. Sheahan gets the benefit of being the only remotely ready top 9 center we have in our system, so it'd take a good deal to get him. It'd also probably have to be for another center.
