Wilson showed so real flashes his freshman year. In that sense, Wilson might more similar to Heaps than anyone else. Though I hope I'm proven wrong on that.
I know people want to gravitate to the Beck comparison because Beck showed what a QB can grow into. But Beck improved each of his four years.
I list the other sophomore starters because I believe that a sophomore who started his freshman year, especially one finished they way Wilson did, to look like a more polished QB than a sophomore in his first year starting. The guys I listed should be the benchmark for a sophomore QB at BYU.
