In the context shown in the article (I haven't watched the press conference), he's talking about their readiness to be the QB and in particular their understanding [I assume of either the offense or how to be a leader] and respect from their team mates. I see him trying to give credit to LDR for helping them learn to be leaders and prepare for games by watching film. ...not that he's no going to help them prepare, but what he has done (and will continue to do) because of who he is (mature, serious-minded, leader, student of the game, etc.).
The tweet seems at best easy to misinterpret and at worst misleading. Here's the context in his article.
... The Florida Gators will enter spring football camp with a quarterback battle on their hands. What separates the two quarterbacks that will compete for the starting job?
“They’re close. They’re real close. There’s probably about a half-inch difference between them, I think,” McElwain joked. “I don’t know. Kadarius is smaller, though.”
McElwain will give early enrollee Kadarius Toney a chance to play quarterback this spring. Toney was told during his recruitment that he would have the opportunity to play quarterback and Florida is low on numbers, but this is truly a two-horse race.
This won’t be the first spring camp for Feleipe Franks and Kyle Trask; both enrolled early prior to last season and had the opportunity to go through a spring camp. In that spring game Trask completes 4-of-7 passes for 63 yards. Franks struggled. He threw three interceptions on 5-of-11 passing, but did connect with C’yontai Lewis for a touchdown. After the spring game the duo was destined for the sideline, calling in signals for Florida’s starting quarterbacks.
“Their understanding and really the respect of the team piece as far as how they go about their business has been great,” McElwain said of the two quarterbacks. “Not to be overshadowed there is Luke’s involvement in helping them prepare to be a starter.”
