He is injury prone, turnover prone and inaccurate. It is a no brainer to bring Hartman in. If Buchner ends up proving that he is better, then he can replace Hartman. If not, then we will all be glad that we got Hartman. If the reason for not bringing in Hartman is that it might upset the chemistry in the QB room, it is just silly. Just as silly as not bringing in a transfer in 2022 for the same reason.
