Always possible. Just know that he's slightly under 50% on touchbacks for the season.
Good stat to know. What I would like to know is how the Packer kickoff unit compares this year, to last year's unit, in average starting position for the opponent. I think that gives us more information. Now granted, you have to take into consideration other factors. Such as the other 10 guys on special teams, as well as opponents, game conditions, etc.
There is no doubt in my mind that Carlson has the younger and stronger leg (over Crosby). Also, as you pointed out, he is cheaper. However, Crosby didn't miss as many XP's, so there is that.
Bottom line for me. I am pretty happy with Carlson and I loved Crosby. Moving on this year to a new, hopefully long term kicker, made a lot of sense to me and I think Carlson has filled those shoes pretty well for a rookie.
