Well my first and most obvious question would be to ask who it is in Toronto who is calling the shots right now? Word on the street is that Murphy was on the outs, so I actually don't know who is steering the Good Ship Argonaut right now.
Allen was effective but expensive. We have lots of good O-Line guys including a few who just got here and can do a job (Doxtater, Moore) so with the number of guys who are top FAs, the deck was always going to get shuffled. Dejon is about 30 so he'll have a few nice productive years, he's a west coast guy and BC can tell their star at QB that they're doing what they can to get him an O-line. Likely has nothing to do with anything, but Allen did almost get Kelly killed in the playoffs against Ottawa.
And, Isaiah Cage is a free agent too...
Not sure if Varga is a starter or not, but most of our National linebackers got played as a starter at some point last season. As it stands we have Cassar, Sopik(FA), Adeleke (FA), & Varga. So maybe Varga is a hedge against possibly losing Sopik if someone pulls out their chequebook?
Ceresna, Brinkman, Smith, McManis, Amos, Metchie, McFadden, Priester... some our FAs on D
Grant, Haggerty... on Teams
Arbuckle, Cage, Rice, Mackellar, Carey, Coxie... on O
Freeing up salary and churning the roster happens. And the last few years we haven't done a lot of our signings until later on, so I'll try not to let it bug me as I watch good players get poached one by one.
