Don't get me wrong, even if not totally sold at first I ended up loving the trade for Methot. As valuable as Methot is now to the Sens, we shouldn't worry about re-signing him. He is still signed for 2 full seasons. So what they decided to pay Cowen shouldn't matter as far as he is concerned.
Eventually it may come down to a Phillips type situation. If he wants to play here he'll take less money. In a best case scenario Cowen and the other D in the system will mature and play the top spots while Methot drops to the 3rd pairing. When Vochenkov wanted too much they had to let him go you can only pay so much for a shutdown guy. Expect this to happen often as long as the Sens are on a non cap budget. The Sens will know how best to proceed once Cowen, Wiercioch, Gryba, Borocop, Ceci etc... have another full year of pro-hockey under their belts. By next year or the next, I just don't see them throwing a big chunk of money at Methot with so many young guys with potential in Ottawa and Bingo.
