I have had Ebron in a fantasy keeper league. I was expecting a big time TE. He has been erratic. With experience, he may improve in some areas such as route running but a big question mark with him is just consistency holding on to the ball.
I'd say he does not fit Miami's strategy for getting a smarter team in here. This is a hole they need to satisfy, though. So, if options dwindle, maybe you snag him on a short term, low cost, prove it deal.
