Timmins is not Bigras. The only thing similar is they both had a bad concussion. Timmins had a better final year in junior and a much better WJC.
We have to wait and see how he looks in the next year or so obviously, but one of the main reasons Bigras didn't look good when he came back was because of his demeanor. He's a very gentle soul to begin with, and played too timid when he came back.
Timmins doesn't have this demeanor. He's willing to muck it up if necessary. That gritty mentality will hopefully help him get through the mental hurdles of returning from a concussion, and making plays under the pressure of heavy forechecks, but we'll have to see.
