But why wouldn't you do it with picks instead of Draisaitl ?
1st round picks are easy to trade. Players with a $10.0m per contract, aren't...no matter how good they are, the market is a lot more limited.
Theoretically (assuming the offersheet would be in the four 1sts bracket), the Oilers could package two of those 1st, along with a prospect of some kind, to get a really good player...leaving them with two extra picks on top.
Matching the offersheet, and then trading Draisaitl...you're looking at a market of what...maybe 4-5 teams that not only have that specific need, can also afford him, and have a GM who actually believe Draisaitl is worth that kind of money. That's not a big market to get the most out of a deal, compared to the market the Oils could have by dangling 1sts and futures, don't you think ?
