FWIW, I think the best comparison to Pitts is Shannon Sharpe, who wasn't a great blocker, but went over 1000 yards three times in the 90s, when TEs simply did not do that, and eventually made it into the HoF.
Sharpe caught 7 passes for 99 yards his rookie year, 22 for 322 his 2nd year before breaking out. Hopefully Pitts, number one, will land here and number two, will be more like Keith Jackson his first two years and more like Sharpe the rest of the way. No reason it can't happen.
I'm more pessimistic about Pitts making it to Miami than about him having a great career. But maybe, just maybe...
