Brink had Harrison behind him, good receivers, and the last fully functional offensive line WSU would field until this season. With better defense that team should've won at least 8 games. It was all downhill from there.
The biggest issue that Brink had as a sophomore was the pick sixes. He had a fairly long windup on his throws and I think he threw at least three and probably more pick sixes that season that were the deal killers in at least a couple games. It's the reason that I'm somewhat annoyed with Falk throwing the interception against Stanford on the blown up screen play. Regardless of who's fault it was, that kind of mistake was a big factor in our loss to the Cardinal and you have to make sure you learn from the mistake and don't repeat it regularly (Falk and/or receiver). Brink cleaned that up a lot his junior and senior years.
Falk deserves a lot of credit for his accuracy and the caution that he has when it comes to not forcing the ball. He's done a lot better the last few weeks on dumping the ball off and avoiding sacks as well. Brink was a master of that at WSU and it's one of the reasons that he was the rare WSU QB that didn't miss games because of injury.
