Grondin I can see. Size and potential down the middle but Busdeker to Ottawa just makes no sense:
1) He's a Michigan kid so it's not geographical
2) Ottawa has 99s Hoefenmayer (Arizona) and Wilson, 2000s Bahl, Rippon, Roberstson ('18 eligible) and Okhotyuk ('19 eligible), and Peric (01). That's 7 regulars. Busdeker replaces who? He's no better than a 5-6 and might be a 7-8 in Ottawa. Unless Ottawa is moving one of their 7 in another deal (which is certainly possible), I just don't see a fit.
With Ottawa's fairly rich cupboard of picks it would make more sense for them to go after a legit 1-2.
