Langer was a tripper. It's a good tactic when you're that small though. I honestly won't commit to Walsh long term if he doesn't bulk up and work on his defense. The reason so many halfbacks are 'the next big thing' is because they are genuinely talented, and these talents are enough to make them look like superstars until the opposition figures them out. From here most fade away as cracks in their game are exposed and they don't have the creativity to adapt. Walsh may be creative enough, but if he is run at constantly, teams will score points against us. Look at last night.
It's not normal for a FG player to be missing as many tackles as he makes.
