Damn cuz, that is pretty slim pickins. I think Gonzales is the safer bet. I would wait a few weeks before starting Horn. I have no idea what type of rapport, if any, he has developed with Harrington.
3 TE/WR..... I also have TE Gates SD the rule is need to start 1TE and then 2 WR but you can use a TE for a 2nd WR...should have stated that more clearly in orginal post.....Maybe I can trade one of my TE for a better receiver but our league is pretty basic scoring..3 bonus points for 100 yd. game is all.
I'd go with Horn. No matter what you think of Harrington, he is still in a powerful offensive scheme with an offensive line that should give him time. He'll look Horn's way.
