I don't think that's fair at all. He threw everything into trying to become an NFL QB, and when that didn't pan out for him he decided that the next best thing would be a transition to WR. Only after being cut from the Bengals as a QB did he pursue being a WR, which the Browns were the first team to swoop him up. If the Browns cut him from their roster you better believe another team would pick him up as a WR.
He sat on the bench most of last year, and learned the position. I don't think it's a statement on how pathetic the Browns are, rather a testament to how hard TP worked to get something new. The guys sitting behind him on the depth chart are 4th and 5th round picks - our own Michael Thomas was a 3rd round pick and will be lining up as the 3rd WR for NO - just as TP will be once Josh Gordon is back.
