There's somtehing I've been pondering for a while and wanted to hear some other opinions.  With all the talk about roster spots and position battles, I've been thinking about our TE situation.  Heller and Carlson are locks to make the team.  Putzier and Newton are battling for the last spot, but neither of them have seemed steller.  Newton sounds raw, and Putzier is a journeyman who got kicked off the practice field during one session for dropped passes.  Could we keep only 2 TEs and use that roster spot somewhere else?  Would that be a good idea?  The reasons to keep the 3rd TE I would assume are in game injuries and 3 TE sets.  If we had an injury we could just go to more 4 WR sets during that game, like we did last year when we didn't have a  true recieving TE.  Plus, Newton can be placed on the PS to be activated if there are any long term injuries.  I don't think we run many 3 TE sets, but we could just use a backup lineman instead of the 3rd TE.  

Keeping only 2 TEs means we could keep a player like Jamar Adams (unless he beats CJ Wallace outright), Justin Forsett, Owen Schmitt, or Jordan Kent.  We would have an extra roster spot at a position where we usually keep less.  It would help us avoid trying to stash these young guys on the PS and potentially losing them.  Plus I think that any of those players helps the team more than Putzier or Newton.  Their contributions would most likely come on special teams.  Adams and Schmitt should be worthy contributers in tackles, I would like to see Kent try to play gunner on punts and kick offs, and Forsett has been talked about as a return threat.  I dont think Putzier or Newton could do any of those things better than the previously mentioned players.  Do these other players offer more of a value than either of the extra TEs?  Do we need 3 TEs?  Interested to hear thoughts
