I think Konz does some things better and Frederick does some things better.
When it's 3rd and 1, Frederick. When we're 5 yards from the opponent's end zone, Frederick. Late in the game and grinding the clock, Frederick.
If you want a more mobile guy for screens or getting after LBers, Konz. Obvious passing downs, Konz.
NFL.com compared Frederick to David Baas. I think it's pretty apt. If he turns out to be Baas, it will help our running game a ton and keep Tony's pocket clean.
