Quarless seems to have all the physical tools, but struggles with catching the ball for what ever reason. In the 2010 season, Mike McCarthy gave Quarless the shot of filling Finley's role, but once it became clear he couldn't, Mike McCarthy used Quarless as a decoy with great success.
Even though Quarless struggles to catch the ball, he's still got some very good quickness and speed for a TE. Mike McCarthy would have him run straight down field and with would take a Safety up as teams never want to let a receiver open behind them. This would open up a big space underneath where one of the WRs (lot of times Driver or Jones) would run a crossing route and catch it and run.
Ryan Taylor has knee surgery but seeing as they haven't put him on the IR (and could of instead of releasing RB Hill) they're acting like Taylor might be back this season.
As far as Bostick, have they let him on the field on offense at all? The TE coach said they wanted to make him a complete players and not just a receiver before letting him on the field. But I thought he'd make a good possession WR when all the WR got hurt and they didn't try him out there (at least not in the game). So they seem to trying to force him to learn to block before letting him on the field. Which I think bring up an interesting question.
Who will they let on the field on offense first? Bostick, who's the better receiver or Stoneburner who's more well rounded.
