Kempt has put on what 15-20 lbs? He says he's worked hard this offseason to improve his arm strength. That coupled with an improved offensive line and more tailback and tight end options should put him in a great position to succeed. I think big things are ahead and only if KK gets hurt does he not start all the games.
I'm more worried about Butler and Jones catching it than Kempt throwing it. Those two need to be way more consistent.
