It really is a low risk move, but the 2 paragraphs I put in bold do concern me. If Tannehill does play, you don't want a WR out there who's going to be a liability and be in the wrong place at the wrong time. Last thing we need this year is stupid turnovers.
I also tend to agree with Houshmazode. Chad played in a system where guys like Reche Caldwell and Jabar Gaffney excelled, the fact that he did nothing last year really surprised me and concerns me now. I expected him to have a good year.
Granted I agree with the point you and Ck are making with Tannehill especially. Philbin you have to hope can figure that out in training camp before the seaon begins. Two facts that stand out to me is this guy has been very, very productive until really just last year and we have the opportunity to see if he can be just as productive for the Dolphins very cheaply.
