Many have gone through that. Remember James Jones? The first year or two he was here, his nickname was "Alligator Arms". Anytime someone was talking about the Packers and mentioned "ol' Alligatior Arms", everyone knew they were talking about Jones. He struggled badly his rookie year, then improved in Year Two before sucking again in Year 3 and 4.
A lot of fans were really pissed that Ted gave him a decent second contract, but it wasn't as good deal as he'd hoped for, and there was a lot of acrimony. In the end, he had no choice but to shut up and take it, because he learned the hard way that he wasn't worth as much on the open market as he and hs dad thought he was.
Driver went through the same learning curve - dropped a lot of passes his first year, then improved his second year, and by Year 3 and 4 had grown into the DD we all remember. But that first season, I remember a camera angle showing Favre's face as he released a pass to Driver, and he was literally wincing. Could hardly stand to look, and then he burst into a big grin when DD caught it.
I love the Lloyd pick too, but I'm not quite as confident as you seem to be that he'll learn. Ahman Green never did, at least in his 7 years in Green Bay. It wasn't until he went tio Houston that he figured it out.
But every player is different. Different players may have different underlying reasons for their tendency to fumble, and some may be easier to coach up than others. But either way, our scouting and coaching staff seem to think they can work with it, so I give them the benefit of the doubt. In a few months, we'll start to see how it may work out.
