Those alternatives are a headache for the Franchise and a distraction for the team. They were never NOT going to sign him and the price would have only gone up.
Kyler can play and the next coach would be wise to tailor his offense around the talent that they have. (They are loaded on offense, btw)
Love him or hate him, he's about Kirk Cousins level (which is pretty good), with the upside of being young and being able to scramble (before the ACL).
It's not easy finding a QB of this talent, even with Murray's baggage. That's a hard truth.
