Too all the people who are pissed Berg didn't get a big time scorer, remind me again who was available? Jagr: slow as molasses., marginal production now. Cole: been there, done that. Whether or not he kicked the tires on an Iginla or not we'll never know. What we do know is the asking prices for marginal pieces was very high.
Berg got a top 4 defender who can move the puck. He got speed, an offensive upgrade for the bottom 6, and a guy in Mitchell with a boat load of playoff experience. He got all that without giving up any of his prime prospects. Fifth rounders, a 7th and Nevins, a 2nd this year and the potential for a 3rd. He clearly wasn't prepared to part with his first, yet.
He's improved the team's ability to move the puck. He's added speed, special teams proficiency, and the types of guys that often contribute timely goals in the playoffs. Remember Dom Moore in 2010? That's what I think they can expect from Flynn and/or Mitchell. At the very least, they've got a rotation of guys in DSP, Flynn, and Mitchell that can be inserted all over the bottom 6 and provide a lot of jam.
They're not 'sexy' trades, but they can be very effective.
