Dillon Gabriel has a lot on his plate. The Browns have given a lot of complex concepts to Gabriel, one of their two rookie QBs, to study and try out from spring until now in their new-look offense. Now, he’s also dealing with some hamstring soreness and was limited because of it on day 10 of Browns training camp Monday. There’s only so much he can control with the injury (which wasn’t known at the time he spoke to the media prior to Monday’s practice), but in terms of having his playbook plate filled, it’s something Gabriel has gotten used to, even before his first NFL season.
