Uhhh, you're going to need to explain how that was a work of art.... Next year is when the Petes should be good. Lockhart or McTavish would be good next year as a rookie but nowhere near as good as a 2nd year Cuylle would've been. Based on their window (next year) Oke really messed that one up bad. By the time Lockhart or McTavish are ready to dominate, the Petes are probably ready to trade them to rebuild becuause Merkley/Jones/SDA/Chisholm/Gallant/Kirk/Hinz are all graduating the year before
Not really. If the Petes are good next year, the following year they'll trade excess 00's and possibly Nick Robertson since he's the sole good 01 on the team, and get picks and younger players that complement Lockhart/McTavish, who will still only be 17, and whoever they take with their second first round pick (and pick 21, and Butler and Spearing, and Austin, etc...)
The guys they draft this year is more about the Petes next window, when those players are 18/19, then it is about next season. I don't think Cuylle vs. McTavish will be the defining factor in whether they win or lose next season and they undeniably have a ton more assets as a result of the defection.
In fact, if they had Cuylle, his 18/19 year old years would likely be wasted because of the rebuild following next season, so deferring a year in that sense may be better.
