Well, at first glance that would seem odd....but on sober second thought:
Who else from Saskatchewan that was on the West allstar team would you think should be on the CFL allstar team?
On offence, the ones who were West allstars but not on the CFL allstar team are Makowsky at tackle and Flick as a receiver. As good as Flick has been this year, I can see not ranking him ahead of Edwards, Simon, Clermont, or Armstrong (but it's close). I can't see Makowsky as being better than Goodspeed or Murphy.
On Defence, I concur with Johnson not making it at corner, but I think Perry and Hunt should have beaten out Jonathan Brown and Eiben, respectively. However, I cannot argue Lloyd missing out, Moreno and Simpson are clearly superior MLBs.
All in all though, remember it's a team sport....the better team usually wins even if another team has more individual stars.
