Relax folks...
1.) Harry has only played in 13 professional games.
2.) Missed most of TC last year.
3.) Virtually learned all off-season.
4.) Played with Brady for 8 games, Newton for 3 games, and Stidham/Hoyer for 1 game.
5.) Is a WR in apparently what is one of the HARDEST offenses to learn...I mean Ocho Cinco couldn't hack it here...Reggie Wayne quit early...Chad Jackson...Aaron Dobson....and we tried all kinds of free agents like Eric Decker, Kenny Britt, and etc... the only FA's that worked out were: AB (great talent, but a head case), Gordon (sobriety issues), David Patten, Wes Welker, and Randy Moss. 1 is a HOF'er...and two more have a case at least. The only real home grown WR's we ever had that succeed were David Givens, Deion Branch, and Julian Edelman. Two of those left in FA (albeit one returned). Then there was Troy Brown who was already a 5 year veteran in a similar offense before having his big 100+ catch season.
===============
That being said....maybe we need to reevaluate our offense and make it simpler for WR's to get up to speed. Less option routes...and etc...same for the TE's...maybe lock each guy into X, Y, or Z and get them up to speed on the nuances of each spot one by one.
