Mahomes and Jackson are completely different QBs. Jackson had a good year, but is 1 hit to the knees away from being below average. I think the most common comparison to Purdy is Brees. But that is some big shoes to fill. Purdy does not play with that moxy yet. He needs to do that this year. take ISU to 10-2 and a Big 6 bowl and get to or extremely close to the Big12 title game. He should be able to get to it with the roster. A good to above average defense, good rbs, really good TE, above average WRs that should take the next step..... It all boils down to the OL.
