As far as Famous Jameis, the physical skills are there (more than Mariota as Winston is a more pure pocket passer than Mariota................Mentally he was really clutch in several games this past year as his team wasn't as good as year before..........The off-the-field issues and perceived immaturity is a risk for a team to invest that much money in.....Either he will grow out of it or he won't......That's the risk.
Like any new QB coming in the league the #1 goal should be obscessed with being great (the filmroom should be your entire social life especially younger QB's, no time for "turning up" or other social activities due to alot of money after signing contract and letting it go to your head thinking you made it)...This is where some may be hesitant to invest that much money in Winston..........I'm sure teams will interview him many times to get a read where his mind at.
