I agree. However, I think the point is that if Gronk *KNEW* he was done right after the Super Bowl (his words, not mine), then what you describe isn't really the situation.
I suspect that what happened is that during the SB, he knew he was done, but wanted to give it just a little more time to see how his body felt in the weeks to follow. But still...the draft was more than 2 months after the SB...if he knew during the SB, he could have told the team before the draft. He chose not to. He has that right. Football is a very tough business and I wish Gronk nothing but the best. But he could have told the team before the draft (seeing as though, by his own words, he knew his deal) and chose not to. That didn't help the team, but rather, maybe have hurt it. (may have...maybe, maybe not...who knows)
