I love it - why do people (all the press, Tim Graham, dope and his lapdog, most posters) want to read so much more into this than there is? We all hoped that TE could be 5-1 TE rather than the other TE. He showed glimpses in preseason, and was given a bye because the old coaching regime was horrible and was given the start. Turned out - whelp - 5-1 TE is not here - in fact - scared TE is what is left. Why cut him? because it is awkward for him and the team to have him around - simple as that.
There were no worthy QB's in last years draft - so Fitz services the team through the year and Brohm is moved up to #2 so he gets the snaps in practices. Again - no space for TE and you get to see if there is anything in Brohm.
All seems reasonable to me.
