Among the backups, Zack Darlington throws the ball with good accuracy - he tossed a corner route to the end zone just about perfectly on Thursday - generally finds the "right guy" late in the route tree. He appears less likely to force a bad throw because he'll wait an extra beat for the good one. He's savvy. A.J. Bush is long. Long-striding runner, long motion for a passer. Bush has his moments. He's thrown some really impressive passes, including a few on the run. At this point, I watch him and wonder how many ten-play drives he could lead. Ryker Fyfe has received the most snaps with the No. 2 offense that we've seen and he's done OK. He's been more accurate with the deep passes. Armstrong's been better on some of the tougher routes to throw because the velocity on his ball is better.
