Bess will definitely make the roster. I think the issue is more along the lines of whether or not that's ideal if you choose to look a little further down the road. Opinions will vary like everything else.
There always seems to be a fine line among fans between simply developing an appreciation for an over-achiever who makes the most out of what he has, and going overboard with infatuation for a player who needs to be upgraded in order for the offense to achieve a more desired status and compete for championships.
I've always had a great appreciation for Davone Bess because he has to work for everything. However, I also understand that Miami needs more from the position. Miami should want more from the position, and strive to upgrade the punt return unit in the same manner by killing two birds with one stone, so to speak.
It's hard to get around to it when the team always seems to have a dozen other priorities that need more immediate attention. Miami hasn't even made giving him competition a priority yet.
Davone Bess is essentially the Channing Crowder of the offense. A guy who continues to hang around despite the need for upgrade simply because of other priorities. But rest assured, pretty soon your turn at the stake arrives, and I think it'll come fairly soon with a coach like Philbin.
Bess is probably a top-10 slot receiver in the league, but that's not really saying a whole lot. There's probably 7 or 8 slot receivers in the league I'd take over him right off the top of my head and without giving it much thought. Hypothetically, you could even throw in a few rookies who haven't played a down yet like Joe Adams, T.Y. Hilton, Jarius Wright, Devon Wylie, Lavon Brazill, etc. and I'd give you Bess for any one of them straight up in a trade just to illustrate my point.
I understand a little bit where jim1 is coming from here. It's the effort towards upgrading the slot/punt return units that I would like to see, and expect to see.... with the difference being it would've already been a priority on my list.
