I asked the same question. A reporter did in the post game, Rex said because Tim said he was good to at, but then Rex said that he didn't want to play him unless it was absolutely necessary. So it still doesn't make sense why they wouldn't dress McElroy
Dear Tim Tebow,
I'm sorry that you had to play for the New York Jets. I know you make a lot of money and it's your job, but you didn't deserve this crap. I think you'll do fine at your next NFL team because someone there will know how to use your unique talents.
Again sorry about 2012 and the broken ribs...hope you lose your virginety soon.
