Taysom was in his first year of it too. He had some accuracy issues, but the main issue was the O-line. He didn't have much time. The O-line has improved, but Tanner is struggling more than Taysom (partly why Taysom won out last year, aside from the fact that Taysom's legs could compensate for the weak protection). Recruiting to the system will mean bigger and experienced O-line, with an experienced QB.
